Personal Finance

You'll generally get less from a defined benefit plan vs a defined contribution plan. A defined benefit plan is an insurance product, so the managers are encouraged to be more conservative with investments to limit risk. A defined contribution plan is an investment product, so the managers are encouraged to maximize returns.

Would you rather have a 5% yield guarantee or a very high chance at 10% return? (as in, 10% has been consistent in the past) In almost every scenario, a defined benefit plan will have much lower usable cash and no inheritance vs a defined contribution plan.

The US actually has both. Social Security is a defined benefit plan, and a 401k is defined contribution. Social Security is intended to replace ~40% of pre-retirement income (more for lower income, less for higher income), and the 401k is intended to fill in the gaps.

I think the "Pensions you don’t contribute to and the amount you get is fixed." is a bit murky. If you have a pension that probably means you have a lower salary compared to an equivalent non pension job, because part of your labor value goes into funding the pension. But the main thing is 401(k) puts a lot of responsibility on the individual. And as this article points out, if you put a lot put retirement financial planning on the individual, that creates a larger social problem since many people can't sufficiently do that themselves, even if they are being responsible with what they earn.
