Re: Those were the days
"a private company that puts its reputation on the line is a much better guarantee of safety."
I think so as well, at least in the CURRENT environment. [at least one lost space shuttle may have been due to environmental 'concerns', changing the glue that held the insulation on the fuel tank to a more 'environmentally friendly' one, which allowed it to break loose and damage the shuttle's wing, etc., because as we all know, "the environment" is more important than safety and human life... to THEM, anyway - it's their "god". But I digress...)
'Back in the day' the U.S. gummint was more interested in getting technological superiority over their 'behind the iron curtain' equivalents in the USSR, for several reasons, not the least of which WW2 was an ACTUAL MEMORY and nobody wanted to repeat it with the Soviet Union on the other side. And Kruschev was threatening everyone, banging his shoe, etc..

If the threat was not real, he made it SOUND real, for whatever reason.
So NASA was highly motivated to succeed. And JFK was as well. Presidents back then (both D and R) were ANTI-communists, and had memories of WW2, and so on. And so did the people, and the people love heros and want the world to be a safe place, and space became IMPORTANT, and so the motivation to succeed, and take the risks to get there [and pay for it].
I wish it were still that way, because I'd rather buy rockets and fire them into space than give money away for nothing. But I digress...
But now, private industries compete against one another the way the USA and USSR competed against one another. So the motivation is there to "beat Boeing" or "beat SpaceX" etc. and Amazon is in the mix now, and Virgin Air is in there someplace...
So yeah, company reputation and safety records and getting there first. THAT is the motivation!
Profit is good. (Ferengi rules of acquisition, heh). But without profit, there would be no investors, and therefore no 'bucks', and therefore, no "Buck Rogers". You can't be a wasteful black hole of expenses into which money is thrown, if you are a private industry. Take THAT anti-capitalists!
