Seriously, there's tons of more pressing issues back here on Earth, ranging from real, social one like inequity and discrimination, technical/political ones like the ever growing piles of garbage all over the place, healthcare, climate change and mass extinctions, and say, taking care of that whole cycle of oppression and bloodshed that has been going on for a while now (not that it'll go away, but we're pretty fucking screwed if we don't come up with something which will leave most people content).
None of those problems will go away if we send little men on tin cans to space, and in fact, I can think of very little problems that will be solved by that. We're a long way from escaping the mess which we have created here on Earth, and wherever we go we'll do it again, and that's being optimistic in saying that we will actually get a self-sustaining Homo Sapiens population off the planet before our shit catches up with us and we're actually forced to do nothing but deal with the consequences.
