Y’know there’s this thing called Target Retirement Date ETFs right?

Of course I do.

But a surprisingly large number of people either don't, or don't understand it and are terrified of making a mistake, so they end up making the much worse mistake of leaving their 401k contributions in the cash sweep account. (I think in recent years 401ks have started putting contributions in target-date funds by default instead of making people affirmatively choose it, but still, a lot of people lost a lot of years of growth to that issue alone.)

And again, that's not even talking about the people who simply don't [think they] make enough money to contribute at all, but would have had money going to their retirement if it had been in the form of a pension that they never had the option to decline and get in their paycheck instead. I have never heard of a 401k that forces you to put money away in order to ensure that your retirement is actually adequately funded, the way that pension plans used to handle automatically.
