Earlier quoted context omitted.
Slight tangent re: fitness. Over Christmas my dad and some similarly aged people (70’s) were reminiscing about their childhood, and pointed to the lack of Doritos as memorable. Junk food was neither the product of decades of addictiveness-enhancing R&D not cheap. A poor person today by contrast has junk food as the cheapest option.
Cheapest by effort plus taste divided by cost maybe. It’s still much cheaper to buy a bag of rice and a bag of beans and some frozen veggies. You can eat sub $1 meals
When I was younger even though I lived on a major street downtown in a city, there were no grocery stores around. Plenty of fast food restaurants with $1 menus though. Cheap, quick, and easy, but not all that healthy. Actual grocery shopping was a once or twice a month thing - bus ride out to the store in the strip mall, cab ride back, 2+ hours total and a lot of money.
One of the things I love about my house now is that there's a full grocery store right at the end of the street (along with other stores and a restaurant a block over). But most people don't have that.
