Making money is like a clicker game, such as Cookie Clicker. If you are earning a wage at a job, you're still in the boring part of the game where you click to get cookies. Wealthy people are playing the metagame, buying the grandmas and factories and space vortexes that automatically generate cookies. And that's when the game gets fun.
I think our concept of "greed" is a bit misplaced. Greed is not about having more money just to have it. If you or I had as much money as Bill Gates or Donald Trump, we wouldn't know what to do with the huge amount left over after all our needs and desires are met. It's about being able to buy the next thing that automatically clicks for cookies, so that they can continue making cookies (money) faster. Increasing the rate of cookie generation means they're winning at the game. It's their hobby, it's their passion.
