Edits (in case my meaning above is not clear):

1. When I write "but we want the opposite to be true" I mean this: if only Trump-aligned or Trump-tolerant people sign up for these roles, I do not think this is desirable for NASA.

2. When I write "I understand the spirit of this comment (and I get it)" I mean: from an individual point of view, I fully grant that many people would be better off seeking work elsewhere.

3. My experience and scientific research shows that people are not merely selfish actors. While individual incentives matter a lot, perhaps even predominantly, it isn't accurate to claim that we can fully explain human behavior with exclusively narrow individualist framings.

4. Many of us act selfishly much of the time, and this is indeed reasonable and even beneficial at times. But taken to an extreme it can be worse overall, even for those individuals. See: game theory, social connections, morality, and so on.

5. When I write "Let's find ways to support good people who step up" I do mean concrete things such as "let's crowdfund ethical people's legal fees" to survive the Trump administration.
