If you look at a long enough time scale the only correct answer is outer space. Lets be real. Earth is limited. There is only so much space (assuming resources are not an issue) and humanity (myself included) do not enjoy being packed into a smaller and smaller living space. I say screw entitlements, and increase NASA funding tenfold. Let the stupid people take earth, and Ill see you on the beaches of HD40307g (otherwise known as planet Bob)
