People and money have a long history lol. Its always been tied into statures and egos so there will always be people who act like this. Remember, its not about what they think about you, but its all about their own relationship with money - and what they think it means about themselves. The biggest fear humanity have is that they are not good enough... Then if they are not good enough, they wont be loved. It comes out in so many issues in life, often boils down to that.
