The closest stars are way too far to reach on any reasonable timescale. That's not even mentioning the fact that moving forwards is a vague goal. Moving forwards towards what exactly? And if the US government got off of it's ass to... Oh I don't know, maybe fix the bullshit healthcare system we have and help people with tax money instead of bombing people for Israel things would improve quite a bit in a very short time. That's assuming we don't bomb each other over terroritorial squabbles first. In any case I don't really understand your defeatism when it comes to inequality but when it's something as difficult as interstellar space travel you seem to be optimistic.

It's not optimism and defeatism, it's recognizing that one of them lasts and the other doesn't. Political changes like you listed can easily be reversed in future, but if we discover something in space, we'll keep that discovery forever even if we stop exploring.
