If you can consider rich people to be greedy how the heck did they end up becoming rich? I do not believe that rich people are greedy because they know how to put their money at work, they are the most patience in the whole world, they invest and easily expect results after several years later, poor people can't do this, to me the poor are the most greedy because they can't let go, they find it hard to invest money, they find it hard to take risks.
Lol. What the heck are you going on about? Greed is the primary reason why so many rich people stay rich. They usually aren't satisfied no matter how much money they have which is why they keep getting richer and richer.
Also, all rich people aren't patient. Elon Musk is a great example in this case. Do your research!
