There seems to be a myth going around that greed drives the rich.
Here is the problem with that, it's not a myth. It's a truth. There are some rich folks who are questionably motivated by greed, your man Trump being one of them. And you don't have to look far to see evidence of his greed, e.g. Trump University. But others are very honorable and truly philanthropic and altruistic like Bill and Melinda Gate, and Warren Buffet.
The rich are a diverse group. There is no one single stereotypical rich person. Each rich person has their own motivations and their own behavioral drivers. So to lump them as one single monolithic entity as you have done is overly simplistic and just flat out wrong.
What you have done is recite a Trumpian myth; the myth that rich folk like Trump are not greedy.
My theory is that some people become so good at earning money that nearly everything they touch turns to gold. I suspect that after a certain point, earning money becomes a hobby, not a necessity. If you were incredibly wealthy, would you grow dissatisfied with your life and possibly turn your attention towards community service such as politics?
Like I previously wrote, you cannot fit all rich people into a single mold. They are a diverse group of people. For the likes of Trump, money is never a hobby, nor has everything he touched turned to gold. Trump has a long trail of bankruptcies and failed businesses behind him which spans the course of decades and some of them are recent. If Trump hadn't been born to wealth, he would selling used cars down the street for cousin Harry.
If Trump were a philanthropist, if money didn't mean anything to Trump, he would have donated significant sums of his own money to charity and he hasn't. He would sign Buffet's Giving Pledge. But he hasn't. What little charity Trump has done, it was done to further his brand. Because in the end, Trump's brand it is single most valuable asset.
I think that having access to any material possession might have limited value at some point for many people, and would create a need for greater fulfillment elsewhere. Your thoughts?
Like I said, if Trump were looking for fulfillment through philanthropy, he would have done so. But he hasn't. No, Trump is all about greed, but Trump's narcissism greatly exceeds even his greed.
