It's not a statement of net worth. It's a statement that she isn't completely ignorant of what she is talking about.
If a teacher in school corrected your mistake and you said, "Who are you to correct my obvious math error." , the teacher could list her jobs in math and national awards for being a math teacher.
Brad asked for her qualifications. She gave them.
You'd be insane after asking for qualifications to reply , "Well I don't brag about my awards."
NASA and Space Force work extremely closely in a vast number of capacities. There are dozens of ways she could have worked for NASA, and then had her responsibilities extend to assisting space force as well when it was created. Not sure why you desperately need to go out of your way to attack a successful woman, but it's a pretty pathetic look.
Language is intended to convey content. Are you unable to understand what she said and need an adult to explain to you what she meant? While the wording could be less ambiguous, it does not detract from what she was trying to convey. She wasn’t posting a CV, and trying to dismiss her like this feels like you’re trying to come up with any reason to invalidate what she is saying.
To what end? What is the purpose that you feel you need to correct that inaccuracy, because she did not say “A former space communications specialist with NASA and later, the U.S. Space Force” like her actual bio does, even though you, and anyone else reading, understood that context?
She’s someone who distills space science down to easy to consume media to the point she specialized and got a job doing it for the government, so she has credentials to be able to talk about space on social media. That’s all the more she was saying.
