Like I said earlier, a luxury tax. The capitalist utopia of singapore has them. Tax the rich and give it to NASA or create multi-billion dollar seed fund for immortality hacktivists.
And now for the things you haven't addressed. Why is the government the most efficient way to solve the problem? Why cancer or immortality or space exploration are more important than food or malaria or sex education? Just because you like them?
I think you should stop and think real deep about the questions I've stated and implied in this thread, and answer them in length, with references where appropriate. Then share them.
Else all you end up doing is coming across as a naive angry fanatic with not too much reading comprehension skill (remember all this started because you misinterpreted DHH's essay) who doesn't even get to see the problem and is boasting about solutions.
