Those pensions could also be tied to the market, or more often the profitability of the company that ran it. There are many, many cases of underfunded pensions by bankrupt companies causing issues. All being equal, I'll take the job hopping and my own retirement account.

I agree it's more expensive than ever to afford to raise a family, though. There's also a malaise in the air that I don't think broader society has felt since the late 1970s, too.

401k became a thing in part because of deep structural problems with employee pensions. Pensions don't "guarantee" anything in practice and many people lost them or had steep cuts. It is a promise, not a law of physics. 401k/IRA wasn't created for no reason. Pensions are exposed to much more idiosyncratic risk than a 401k and companies are poorly positioned to manage those risks.

Some people might not want to take responsibility for retirement savings in the same way they might not want to take responsibility for providing themselves housing but the alternative is strictly worse.

The only pensions that kind of work is government pensions because they can paper over the structural deficiencies with taxation. But even that has significant limitations as we've seen.

A 401k isn't required to be invested in the stock market. It is advisable but not required.

Pensions are mostly a pyramid scheme scam. It’s why basically all government run pensions have more liabilities than assets and effectively keep taking from taxpayers to not collapse. And why many company run pensions disappear in a bankruptcy.

I prefer having the money under my control, personally.

Those "guarantees" could be lost in a bankruptcy, though. So that world wasn't as ideal as some make it sound.

Losing your job is bad; losing your job and your retirement is a nightmare.
