You asked the first caller why we should care about going out into space because of all the problems here at home. The reason why, in my opinion, is because the amount of resources beyond earth are just waiting for us, and all we have to do is get to them. Imagine infinite free energy would free mankind from fighting over energy sources, building materials enough to build several thousand Earths to give everyone enough space to explore and explore the universe, and even our next stage of evolution. I would say that the investments and sacrifices are worth it.
