Well, am just a 23 years old guy, so the days of the space race were over before I was even born. But still, I imagine it's effect on kids. People you would ask, at 10 years old, what they want to do later on, they would probably say things like "I want to be like Armstrong" or "I want to walk on the moon, too!".
Just look at Felix's jump, it was just a commercial feat and a big-ass advertisement, but people saw it everywhere, and everyone I know was pretty fascinated about it.
Sure, kids won't really strive to jump out of the stratosphere tomorrow. But I do believe that a generation surrounded by events such as faster-than-speed falls and men walking on Mars would be way more profitable in the long run than a generation surround by the latest trends in stupidity and self-importance.
But hey, if we can't see tangible profit in 5 years, there is no way anyone would fund it...
