Five times the GDP of the United States is 65 trillion dollars. That's equal to the current world GDP. Invest it and increase the GDP of the earth by 10% after a slight period of adjustment. Distrubute the revenue from your investments among the world's 6.6 billion people and you give everyone an yearly income of roughly $10,000 a year, eliminating poverty. The 65 trillion is enough money to stabilize climate change (say $7 trillion), eliminate malaria (say 20 billion), hunger (say a trillion) and poverty.
