I've tried to get excited about private spaceflight but I can't. It always feels like someone else's accomplishment, not the nation's.
It doesn't need to be the nation's. Just yours. Go get a job at SpaceX, or Armadillo, or Bigelow, or Virgin Galactic, or Copenhagen Suborbitals, or the new Google-funded-asteroid-mining project. Or start a nonprofit. Or go mow some lawns and then write a check to Copenhagen Suborbitals (they're actually a nonprofit). Of course, I think for most of us nerds, the excitement isn't "gee whiz, I'm helping", it's "gee whiz, I could FRICKING GO THERE".
Taxes are the means by which the majority that does not have wealth, keeps in check the minority that does. If everyone would pony up their fair share, and if we could get our budget in check(including trimming the fat from the military and some of the pension programs that have gotten out of hand at the state level), we could fund NASA and these missions. If we did that, everyone would own these accomplishments. The American people would once again feel pride in their nation. People would once again be excited about space travel and the future of mankind.
So you're saying taxes are bad and oppressive but also good and patriotic? Also, inflation is actually a mechanism by which the rich (bankers) keep the less wealthy in check by sapping the worth of their earnings & savings. Taxation is how people with power over guns and jails keep everyone in check.
