The reason why people are so bitter perhaps is more related to in many cases, our growing up with the awe inspiring and real promise of the whole human race going, together, into space, so we all developed dreams that perhaps have been let down by changes since then.
But that doesn't mean they wont happen. Its quite possible that they will. We're just at a stage, all of us, the human race, where we've temporarily stalled.
However, the space accomplishments we share including the moon landing and ISS and the various space missions by a great many countries and commercial entities are real and we all, nomatter where we come from or do, should be proud of them.
Because I spent a long time working in research in the Bay Area and was a very early adopter of web technology, I've worked for a lot of different entities some of whom helped publish NASA data. (and all sorts of other things)
A very long time ago I was also one of a very long list of talented people who helped develop tools and policies to leverage that data better, making it much more useful and available and cite-able.
NASA was at that time (and I am sure still is) a very high-functioning organization made up of great people who get a very high level of performance out of a workforce who genuinely love their jobs.
Also, contracting organizations that interact with them are also great people and great places to work, that strive, hard, to prevent anything that even remotely suggests unprofessional behavior.
They are probably as good as it gets anywhere in the world of contracting employment.
I was spoiled by my time in the research community, in a sense. I do think that all work should and likely someday will be more like that than what most jobs are like today.
I want us to realize that every mind thats wasted by lack of opportunity and frustration is a real tragedy.
I'm pretty old now, but am still very into science.
The major thing that I wish I had but lack is a better knowledge of math.
