What Do We Get For That?

The total actual 2024 budget to run the country was about 7 trillion dollars.  That means the NASA budget was only 0.004 of the national budget -- less than half a percent.  For every hundred dollars the US government spent, it put 40 cents in the bucket for NASA.

And what do we get for that?  The Universe. 

Missions to Mercury, Venus, Jupiter.  Landers on Mars, telescopes that peer through the depths of the cosmos, a fleet of spacecraft monitoring the Sun, the star to which we owe our existence.  The abject awe and wonder of images of a glorious cosmos.  The first A in NASA is for Aeronautics, too; research that makes air travel better, faster, and safer.  NASA science includes observing and monitoring our own planet as well, making satellites that track our water, atmosphere, and land. NASA scientists study climate change, one of the single biggest existential threats to humanity.

NASA employs about 18,000 people across all 50 states (and that doesn't include contractors, of which I was one for many years, and people such as  academics who have NASA grants).  NASA partners with space agencies around the world, a diversified portfolio that guarantees the best scientific research always pushing past the cutting edge and accelerating our understanding of, well, everything.
