Piling on with the pension comment.
My mom just retired without even factoring her 457 (or old 401k from before she went to public sector) into her retirement plan. She's been working for longer than she needed to because she budgeted retirement entirely based on her pension and social security.
I think a lot of people don't even conceive of an annual withdrawal rate from their retirement savings, they think that's just a giant savings account to cover the big infrequent things like cars, medical events, or a new roof on the house. That's part of why Americans are so obsessed with owning their houses rather than renting—if they don't have a pension, they're trying to think of how to live off social security, and think the only way to do that is to not have a monthly rent/mortgage payment. We know that if you put the value of a home into an index fund, you're dividends and returns will safely pay the rent in perpetuity, but Americans are not financially literate enough to realize that investments are an income stream, not just a big savings account.
