Why are you making value judgements on people's time management?
Personally, I don't understand how anyone who makes over $20/hour ever cooks.
I can buy a great meal for $20. Given my hourly rate of $100/hour, I'd have to be able to prepare an equivalently good meal in just 12 minutes. That doesn't seem likely at all—especially because this analysis doesn't include the cost of ingredients.
Have you considered that many people just don't enjoy cooking? I find your post incredibly laden with value judgements. Why can't you just accept that many people don't share your priorities?
