Well, if billionaires want to give their money away this way... that is what the American system intended! Charity, not socialism.
The problem is that noone wants to do charity a-la-Rockefellers and Vanderbilts any more... because they are already taxed so much that they feel no need to start universities, donate thousands of libraries, build national parks, etc.
This guy should be setting a trend! That trend is that people with billions... should be giving it away. Not having it extorted from them by a corrupt socialist government... that will just waste it (while becoming rich themselves.)
How many millionaire Senators and Congressmen are there? How many were multi-millionaires when they started.
Seeing the problem?
