Money. You have this weird unconscious pecking order thing in your culture where you value people more based on their bank balance. You show a weird unconscious level of respect to someone who is rich. And similarly, unconsciously look down on someone poorer than you. Not in a mean way - just as a “I’m better than this person” way that is hard to quantify. You are aware at some level roughly how rich everyone you deal with is. I see this trait far less in people under 20. I hope there’s a cultural shift on this one, because money on its own is a weird way to measure someone’s worth.

Others have written on this far more eloquently than I have, and so I will use their words to help explain this.

‘It ain’t no disgrace to be poor, but might as well be.’ It is in fact a crime for an American to be poor, even though America is a nation of poor. Every other nation has folk traditions of men who were poor but extremely wise and virtuous, and therefore more estimable than anyone with power and gold. No such tales are told by the American poor. They mock themselves and glorify their betters. The meanest eating or drinking establishment, owned by a man who is himself poor, is very likely to have a sign on its wall asking this cruel question: ‘if you’re so smart why ain’t you rich?’ There will also be an American flag no larger than a child’s hand glued to a lollipop stick and flying from the cash register.

Americans, like human beings everywhere, believe many things that are obviously untrue. Their most destructive untruth is that it is very easy for any American to make money. They will not acknowledge how in fact hard money is to come by, and therefore, those who have no money blame and blame and blame themselves. This inward blame has been a treasure for the rich and powerful, who have had to do less for their poor, publicly and privately, than any other ruling class since, say, Napoleonic times.
