Based on some rough numbers, NASA's budget (around $24B) would be <4% of the US's total spending on entertainment, with a pretty great return in research, engineering and education to boot.
I also looked up the NSF's 2024 budget, which, at $9B, was much lower than I expected.

If a company could spend 24B in research they would probably produce a lot more things than NASA
NASA does both manned and unmanned stuff. Don't conflate those when you are looking at returns.
Look at this joke of a list https://www.nasa.gov/missions/station/20-breakthroughs-from-... for an illustration. And those were the 20 best things they could come up with.
