Cooking is one of those things you have to do at least twice a day so I can’t understand not taking the time to learn unless you live in New York City and only have a hot plate or something.
Because you don't have to do it twice a day. We live in a society of people with lots of skills so having others that handle the cooking and you handle some other important beneficial task would be fine.
And then to fill space between wanting to eat what everyone else is having, using preserved or easy to eat items at home would fill the gap. That would be a rational society though. But we all need to be individually independent.
