Social Classes

It's pretty amazing how people in poverty manage to survive with so less money. When I imagine my self being in poverty, i feel as though i can't survive in such a small world. But when people want to make their lives better by hard work. they are still looked down on either by their families or friends, saying things like u'r trying to b someone u'r not. but the wat i don't understand is that if you can work hard to obtain money or u can make u'r life then, wat's so wrong abt it? i mean u r working for it right?
