food nutritional quality i can afford the 1$ greaseslab but not the carrots
with shelter think about having to live farther from the business district spending more money on a longer bus to get to work.
cars i buy a junker cause that's all i can afford it breaks, i spend more money to fix it all because i couldn't afford the extra 1000 to buy a slightly more reliable car.
It's not true of food.
It's not really true of shelter except maybe rent vs buy.
It's not true of cars, health insurance, or entertainment.
