Did you grow up in a town with dirt roads? Did your neighbors live in cardboard and aluminum self-made housing? Did your family struggle to eat and everyone around you is so skinny that fat people are a rare sight? These are some markers of being poor, and most "poor" people in the U.S. cannot imagine this life. People talking how they are poor because of their stock wealth... poor people won't even have this on their horizon.
Also, yes, my family was very poor in Latin America, and that is why I had no childhood and worked literally all my life, having little friends and romantic life. There are just not enough resources to even do what "poor" people in America take for granted.
