Not really, history doesn't bear that out. The wealth, mostly gold, that came back to Spain from its adventures in the New World started an inflationary spiral that eventually ruined the Spanish empire and left it one of the weaker nations in Europe, which it's been ever since....there has to be a viable financial plan for space, there was for Columbus.
Right, the shuttle was perfectly safe, never lost a ship or a crew. I don't think you have even a rudimentary understanding of what you're talking about. If you think sending people in an environment that's more or less instantly fatal without complex and expensive protective gear isn't dangerous, let me be the first to invite you to step out onto the surface of the moon for a run wearing only shoes, shorts, and a t-shirt.... the tech to go there is 40 years old, this is not dangerous exploration any more.
