This ratio of wealth to income is at an all-time high.

It reached over six during the dot-com days and almost seven during the real estate bubble, but the subsequent downturns brought the ratios back down to that average of 5.5.

Of course, not everyone has seen their wealth increase so much.

The main beneficiaries have been homeowners and investors in stocks, particularly the wealthiest of investors.

According to the Federal Reserve, the top 10% own 87% of all equities and mutual funds.

But the good news is that many people of all income levels have benefited from the current bull market.

According to a recent study from BlackRock, more than half of Americans living on low and moderate incomes, defined as annual incomes ranging from $30,000 to $80,000, now own stocks.

The majority are new investors who began investing within the past five years.

And now for the number of the week, which is 23%.

That's the percentage of Americans providing financial support to aging parents, according to a survey from LendingTree, and another 23% expect to have to provide such support in the future.

58% of respondents who financially support parents have taken on debt to do so, and 74% say it prevents them from achieving their own financial goals.

I don't know about you, but my wife and I don't want to be financial burdens to our kids, which is additional motivation for making sure that we have more than enough to pay for our retirements, potential long-term care expenses, and possibly living well into our 90s.

When saving for your retirement, which type of account should you choose?

That's our next topic of discussion when Motley Fool Money continues.

When saving for retirement, the first decision is how much.

But the next decision is where.

Do you contribute to a traditional retirement account or a Roth?

By far, the majority of retirement assets are in traditional accounts.

But here to talk about the benefits of contributing to a Roth or converting a traditional account to a Roth is Fool contributor Dan Kaplinger.

Dan, welcome.
