I'm Heather Berger from Morgan Stanley's U.S. Economics Team.Sarah Wolfe: And I'm Sarah Wolfe, Senior Economist and Strategist on Morgan Stanley's Thematic and Macro Investing team in the Global Investment Office.Heather Berger: Today, the K-shaped economy, the middle class, and how AI could reshape both.It's Friday, September 11th, at 10a.m. in New York.The K-shaped economy has been a major theme this year. At its core, it describes an economy where households are experiencing very different circumstances. Those with more assets have benefited from rising wealth, while those with less wealth remain more dependent on income and more exposed to increases in essential costs. But that top versus bottom framing can miss an important part of the story: the middle class. Sarah, you recently wrote about what it takes to make it to the middle class in America. How would you define the middle class today, and how does that differ from the way that households define it themselves?Sarah Wolfe: I think the important thing here is that economists and households define the middle class very differently from each other, and, and I'll get into why that's the case.So if you're an economist, the middle class is roughly defined as two-thirds to twice the median household income, which today means if you're making around fifty-five thousand dollars a year to a hundred and sixty-eight thousand dollars a year, depending on where you live in the country, that is roughly the middle class. And that's where about half of Americans sit today.We've actually seen that number decline, so sixty-one percent of Americans in the 1970s were in that middle class definition by economist terms. Now it's about fifty percent, so we have seen it shrunk. But even though it's shrunk, fewer and fewer households feel like they're in the middle class, and they don't define it by necessarily income or a specific number, but they really define it by milestones, I would say.So do you own a home? Have you been able to build a family, and can you pay for childcare? Have you saved enough for retirement? Do you have an emergency fund? Are you constantly stressed about your bills? That feeling is really what the middle class is about today, and I would say that less than fifty percent of Americans actually feel like they're in the middle class once you start to put that definition around it.Heather Berger: What are the key factors that actually make a household feel financially secure?Sarah Wolfe: I think there's four things that determine household security and stability. The first, of course, is income, stable income. Do you have a job, and do you think you're going to continue to have a job six months from now? We love the University of Michigan Consumer Sentiment survey that asks consumers this.Do you have affordable fixed costs, like housing, childcare, healthcare, and transportation? Do you own assets? This is critically important because if we look at where gains have come from from the last five years, it hasn't really been that much through the labor income channel. It's been through the asset channel, like home equity, retirement savings, are you invested in the stock market, et cetera.And then the last one is this emergency fund and a manageable debt. What is your debt load? Is it fixed rate, or is it revolving? The more of these pillars that a household has, the more financially fulfilled and comfortable they are, and the more likely they are to feel like they've made it to the middle class, but the reality is, is that fewer and fewer households are meeting these four boxes that define the middle class by historical terms.Heather Berger: And what has made that security harder to achieve? Which of those costs that you mentioned have moved the furthest out of reach?Sarah Wolfe: I think these numbers are going to maybe surprise our listeners, but in some ways feel very real to them as well. So if we look at how much inflation has risen since the 1970s, shelter, the cost of housing, has risen 6.6 times more than the overall inflation basket. Childcare costs have risen by 14 times more than the overall inflation basket, and healthcare costs have risen 10 times more.And if we dig more into childcare, we now like to call it the second mortgage. And we're not being sarcastic or anything. The reality is that to send two children to childcare in America costs more than a mortgage in 45 states, and costs more than rent in 49 states.So it's really, this reality has gotten a lot more expensive, and these baskets, these individual things like childcare, healthcare, shelter, that define the middle class, have risen more than the overall inflation basket, and certainly have risen more than income growth over this period as well.Heather Berger: Right. So the overall inflation measure can kind of understate the increases in some of these essential costs. And when people talk about a K-shaped economy, the middle class itself isn't necessarily moving as one group. You mentioned homeownership a lot. How much do homeownership, age, and geography determine who is moving up and who is getting squeezed?Sarah Wolfe: Homeownership is always incredibly important, right? Because it's this large asset that is more equally distributed across the income distribution, as opposed to if we think about equities, and you've done a lot of great work on this. That is the most highly concentrated asset across the income distribution, right? Where the top 20% is sitting on 70%, at least, of equities. So homeownership remains the best channel towards wealth accumulation. Obviously, though, timing of homeownership matters a lot. If we were all so lucky to have bought a home in 2019 and 2020, we got a low fixed-rate mortgage, and we would've benefited from the tremendous run-up in home prices over the last five years, right, over 50% home price appreciation over this entire period. So that's been really important. Also, geography, where you bought a home, did that benefit from the COVID home price appreciation? And then the geography also matters because someone living in New York versus someone living in the Midwest is living with really different fixed costs, realities of fixed costs, and that's also gonna help define do they feel financially secure, and do they feel like they're in the middle class?The other component I don't wanna leave out, though, equities is really important. And we did some work looking at the Fed's distributional financial accounts, and if you look seven years ago, Gen X was doing way better than Gen Y or the millennials were at that same age 15 years ago. But then, because the millennials were sitting on so much equity wealth because they've built up their 401Ks, they really couldn't get as successfully into homeownership, so they had more stored away in equities. They have now surpassed Gen X at this age, two and a half times. It is a tremendous reversal in wealth and in who's doing well, and it's because of what's happened in the stock market. And it's not because they were better savers. It was just a lot of timing and luck. So I would say that our fate is not prewritten, as we also think about Gen Z entering the workforce and becoming wealth builders.I want to dig in, though, to a really important part of the K-shaped economy, though, and that's AI. We can't talk about anything without talking about AI, for better or for worse. And that the common view is that white collar, high-income workers are the most exposed to displacement, and we're seeing that in some of the job numbers recently, right, where tech and financial services are shedding jobs. But your work, I think, is really unique, and it's the only thing I've seen on this that argues that that's only part of the story. So what are we missing about how AI is going to affect high-income households in the K-shaped economy?Heather Berger: Yes. Yeah, I think it's hard to talk about the economic outlook, the consumer outlook these days without thinking about AI. And as you mentioned, I think really the main focus so far has been potential white collar job loss, and this, of course, is an important channel. Labor income is really the main driver of consumer spending. But there are also several other transmission channels through which AI will affect consumer balance sheets.And so ultimately, you were just talking about equity wealth, AI will also affect asset markets, which we've already started to see. It will affect consumer prices and policy decisions, and each of these will flow through to consumer spending and consumer credit performance. And so since different subgroups of consumers differ in the types of goods and services they buy and the composition of their balance sheets, the effects will not be uniform across the spectrum.As we've seen with past innovation waves, AI has the ability to potentially widen income and wealth inequality, or it could help to close the gaps.Sarah Wolfe: Can you dig a little bit more into some of these other channels outside of the labor market? So what is the wealth channel, and how does it filter through to high-income households? And then what also is the inflation channel that we should be looking at?Heather Berger: Sure. So the wealth channel is really important for high income consumers because they have equity wealth that is very elevated relative to their labor income. So for that top twenty percent cohort, their equity wealth is around six times their annual labor income. Whereas for the lower income groups, they're about in line with each other.And so even if the marginal propensity to consume out of income is higher than that out of wealth, for this high income group, asset markets are still a really important driver of spending. Now, for lower income groups and really across the spectrum, of course, inflation will be important as well and will really help determine purchasing power.When we think about the price channel, we're really thinking in two phases. The first is that in the near term, AI could potentially create price pressures. So if we look at areas like electricity and software, we've already started to see that the demand from AI has led to increases in these prices. But over the longer term, we are expecting that eventually AI will lead to productivity gains, and therefore could lead to disinflation.Sarah Wolfe: In which categories are we expected to see disinflation, and who does that benefit?Heather Berger: So we're really first expecting to see it in the industries that have higher adoption rates. And so far those have been industries like financial services, tech. And so if we think about these services categories of spending, they really make up larger shares for the high income group, the older group. And so we do think they will benefit first from that disinflation channel.Sarah Wolfe: I think if I sum up some of the key takeaways, it seems that the balance sheet is more important than income, and it's going to continue to be so. If you look at the top 1% wealth percentile, they're holding 70 times more wealth than the median wealth group, and that used to be 33 times in 1963, right? So that gap between those in the middle versus those at the top has widened, and this dynamic with AI is only probably going to continue to widen that gap, making people feel less and less secure about their finances, making it feel harder to be in the middle class, and in particular, making it feel unattainable to reach the next class, right, because that gap is so large. And so we'll be watching as a lot of these dynamics play out.Heather Berger: Right. So asset markets will be just as important as labor markets in figuring out how the K-shape economy will evolve.Sarah, thanks for taking the time to talk.Sarah Wolfe: Great speaking with you, Heather.Heather Berger: And thanks for listening.
