Not to worry, I have the answer. NASA's budget is 0.48% of the overall US budget. That's not even half of one percent.
I don't think we need to wait on space exploration until everybody thinks the way you do. If we do, it will never get done. Humanity will never be perfected, to be human is to be imperfect. To disagree, to fight, to be a mixture of good and bad qualities. We were like that ten thousand years ago and if we're still around ten thousand years from now, we'll still be the same way.
