Edited to add: In my experience, if you don't date someone who "can adult", you will have to parent your partner, which doesn't go all that well if you're not kinky like that.

Your requirements per a "functional adult" are an example of people asking for too much because they have no practical understanding of reality:
Americans don't eat properly. The average American is overweight.[1]
Americans don't know anything about taxes.[2]
Americans don't understand cost of living. Barely anyone knows what the CPI-W is or how it differs from the CPI-U.

I also wouldn't consider CPI-W and CPI-U to be cost-of-living concerns. I consider being able to say "hey, honey, we can't spend 500$ on your mobile game because eggs cost 7 for a dozen at the grocery store this week, we need to revise our budget" to be adult behavior.
Fat people truly adhering to proper eating don't stay fat. Cost of living and budgets are two separate but related topics.
Savings rates being at all-time lows doesn't mean that people don't know how to budget. It might be that budgeting has become much harder. Similarly, I don't think someone being fat means they don't understand how to cook a healthy meal. It might be that keeping thin has become much harder.
