What is the point of goin to college earning a degree if you are just going to be cheap?

My older sister 29 lives in a world of cheapness. If I was her I would be shopping for designer things driving an expensive car. My sister makes good income but I see no point she cheap shops at dollar tree , comparing prices. And she drive an old 2012 car. She lives in a mobile home because she does not want to pay yearly association fees at a nice neighborhood. My sister even wears Dollar tree make up because in her opinion a $20 Sephora make up is to expensive. Girl I work at subway and i still buy my slef Mac cosmetics. My sister should even be on that show extreme cheapskates. She so cheap!
