Some of those jobs are important(1), but most replacable - many people can do that job.

And I'm not saying thry don't carry done value , just that raising your kids well, in my view, is much more important.

The idea seems pretty ubiquitous, as soon as a society gets any amount of wealth you'll find people being paid to cook food at scale.

And cooking is one of those things that scales up very well, it doesn't have to mean fancy sit down restaurants. There are still a few places I can grab food for cheaper than what I'd be able to prepare it myself at that quality level, though sadly those types of venues have seemingly been on a decline for decades.

With modern preservation methods, factory made food can reach very high quality. Google the french chain picard, or micvac.

Maybe not for fried food, and salads(easy to make). but for most other types of food it can work.
