I could refer you to any number of excellent histories of the Apollo program. Almost no one thought we could actually put a man on the moon and return him safely to earth (to coin a phrase) in the mere 8 year time frame demanded by Kennedy, but this government-run program (in partnership, of course, with multiple private corporations--it could not have been otherwise) was wildly successful. "Slow and bloated" needn't characterize all governmental activities, and isn't absent from the private corporate world. Leadership is what makes the difference.
The USA has changed a lot since those days. People were more patriotic. There was no social media or internet or CNN. WWII was a recent memory. Yes that whole program was magnificent. My post refers to todays USA. No disrespect meant towards our accomplishments back in the day. There is no way we could pull off something like that now.
