Or we could ... I dunno ... spend a shitton less and continue to explore Earth for said resources?
The shite we're looking for up there isn't found in abundance on Earth.
Sad to say, but off-Earth resources will not be economical until the launch cost is less than drilling into Earth.
And that won't happen until we have a space elevator. Its a hell of a lot simpler getting the supplies back to Earth than it would be getting them out of Earth's orbit. All they have to do is drop it in Earth's orbit and calculate where it will land (with a parachute of course). Once the Moon becomes a more primary point of launch compared to the Earth, it becomes more economically feasible.
Hey, but instead of advancing ourselves as a species, let's continue to bomb brown people which costs 20 times more than what it would cost to set up a great space program, which would increase our morale and our chances of being charge for the foreseeable future. Its people like you that would shut down the whole thing and not return until it was too late and we've already lost the Space Race. But yeah, lets continue with bull shite wars that I don't think anyone could rationally tell you why we're still over there, instead of doing something great for a fraction of the cost.
