There was this experiment done in universities

It goes like this, a bunch of people play monopoly. One person starts with more money, gets double for crossing finishing line. The others don’t get any money for crossing the finish line, the rich player gets two dices while others only have one.

As the game goes on, the rich player, who is picked at random, always began to act more dominant, boastful, and even rude. When they eventually won the game, they never think they had any real advantage, they are simply so good at the game, have some tactic.

They never consider this is because of how the game was setup.

Why rich people tend to think they deserve their money

A psychology experiment using a rigged Monopoly game reveals how inequality replicates itself.

The experiment was done by Paul Piff at UC Berkeley, where participants are randomly assigned to be a "rich" or "poor" player in a rigged game of Monopoly.

The results consistently show that the "rich" players, despite knowing the game is unfair, become more arrogant and less empathetic, attribute their success to skill, and become less sensitive to their "poor" opponents' struggles. They also tend to act more dominantly and less considerately of resources.

The experiment has been replicated countless times.
