The original thread title was such an easy question to answer in a broad sense.
People that can’t afford things see them as worthless as a defense mechanism. Schools, cars, handbags jewelry, shoes, designer anything, nicer/bigger home, vacations, the list goes on and on.
It’s easier to not feel bad about yourself if you don’t find or attach value in things you can’t attain. Human nature.
And if one has never experienced of any of those, they have less ability to understand them, but it is usually more about willingness to understand than ability (again, defense mechanism).
