That's a two-edged sword. Food, clothing, cars and all sorts of factory produced stuff are significantly cheaper today than they were 50 years ago. So they don't dominate budgets the way they used to 50 years ago.
I remember reading years ago that food used to cost 30% of a family's income in the early 1900s
Yes, so why are we ignoring that housing is multiple times more expensive? Even with 5 times the luxury expenses, you're not going to end up cheaper than boomers who paid $1000 on a mortgage in a high COL area. Telling people to penny pinch on buying Netflix subscriptions while rent is 70% of their budget is just political theater at this point.
