The sad thing is that a majority of Americans aren't greedy. Most want to work, pay their taxes, have children, watch saturday football and pursue happiness in that manner. Some other Americans want to pursue happiness by making money, lots of money. Maybe there is a greed gene? Why, for example, does Mitt Romney need more than the 250 million he has stashed overseas? How much is enough for the Romney's of America? As for hard work, the hardest work some rich do is carefully select rich parents. Trump combing his hair might be the hardest work Trump does. Now I have to wonder who does comb Trump's hair?
So much here that indicates a woeful lack of understanding about the world and everything in it, I'm not sure where to start.
First, there's nothing "greedy" about continuing to work even after you've made enough money to live on for the rest of your life. Some people just like what they do, and who are YOU to tell them they have to stop because it's "greedy" to make more money?
Second, where do you get off declaring any particular level of income or lifestyle more noble or moral than any other? Just because YOU like getting by from paycheck to paycheck does NOT make it the pinnacle of What Is Right and How Things Should Be. Maybe I want to make enough to leave each of my three children financially set for life. Who are you to tell me that's wrong, or that I shouldn't want that? It's MY money, MY time, MY labor, and MY choice.
Third, who are you to decide what others "need" or not? Can you display a little more hubris there? For that matter, who are you to decide that only "need" - as defined by you - is acceptable and moral at all? Did Mitt Romney break any laws accumulating that money? No? Then what's it to you what he has or does in his life?
Fourth, anyone who thinks Donald Trump became and remains wealthy by "doing nothing more difficult than combing his hair" obviously knows so little about financial success as to actually make me embarrassed to even be talking to him. It's like having an economics discussion with my dog, except my dog is at least cute and pretends to be listening.
Fifth, and finally, let me explain something in a bit more depth that you've obviously never in your pointless existence considered: not everyone works at loser jobs they hate for the sole purpose of paying the bills. Some people do what they do because they enjoy it and have a talent for it.
Case in point: My favorite author, Stephen King. Mr. King is one of the wealthiest living writers on the planet, based solely on his book sales and the investment of the money from same (as opposed to Danielle Steel, who is at least as wealthy from marrying a multimillionaire as she is from book sales and such). He at this moment is in possession of enough money to keep himself and his wife in luxury the rest of his life, and THEN to keep all of his children in luxury for the rest of THEIR lives, and probably his grandchildren as well.
By your standards, you should at this point be screeching in outrage, "How much money does he NEED? Why does he keep making more? Does he have some sort of greed gene?!" Because, despite the vast wealth Mr. King already has, he perniciously insists on continuing to write and publish books. He has all the money he "needs", and yet he continues to work, rather than retiring and sitting around picking his nose. The nerve!
This is because Mr. King ENJOYS his work. He stopped doing it for the money a long time ago, and never was entirely doing it for the money, anyway. He does it because he has a talent for writing, and he enjoys the process of writing, and he enjoys entertaining the people who love his books and would be sad if he stopped producing them (not to mention putting whole rafts of employees at his publishing company out of work).
What, you might ask, does this have to do with people like Mitt Romney (or Warren Buffett, for that matter)? Simply put, they continue doing what they do because they ENJOY it. They have a talent for it. The money is largely just a way to keep score in the game they're enjoying playing (and frankly, after a certain point, it's nigh-on impossible to make it STOP multiplying). Warren Buffett, by all accounts, lives quite frugally for a billionaire. He continues to play the investment and financial game because that's what he's good at, and that's what he enjoys. Mitt Romney continues to manage his personal investments and play the financial game because that's what HE'S good at and enjoys (and because it allows him the free time to do the other thing he likes, which is running for political office). Who the hell are you to tell them they have to abandon the things they like to do just because YOU wouldn't do them if you won the same amount of money in the lottery tomorrow?
