There’s an income threshold where eating out/ordering in becomes viable as your main source of food. There’s another line where you can hire a full-time maid who’ll do the cooking for you in addition to other chores like cleaning.

Once you clear that second threshold, and especially if you have a family, it seems to me that most people prefer it over restaurant-centric eating. Also, if you’re used to prices in major tech hubs, it might surprise you how common it is that a full-time maid is much more affordable than eating out.
