EDIT:
It´s a shame this thread gets hijacked too the "Should rich people give more" or "Should the rich be forced to give money". Its their money, so they are free to do whatever.
The only question i'm asking is WHY do the rich rather go on investing, buying stocks, etc. to make even more money while they allready have more than they could spend in 10 lifetimes, instead of investing it in something lifesaving? If you have more than you could ever spend, then why would you need more money? How can so many rich people think of retarded ways to blow and spoil money while so much good could be done with it.
If you had 10 billion dollars, and you had to blow 9 billion dollars on something, why not pick cancer research or wildlife preservation instead of an investment in Marlboro? It's not like you need more money, so why is there such an urge to make more? Instead of using ur wealth to be another random rich guy with 5 yachts and 30 cars (which u can still provide a lifetime for with that mere leftover 1 billion), why not do something huge for society, wildlife, sickness, poverty, etc. That is what leaves a legacy.
