Your post started out talking about labor laws but then switched to the FDA, which is very different. This is one of the reasons that people like the DOGE employees are tearing things apart. There are so many false equivalences on the importance of literally everything the government does that they look at things that are clearly useless and start to pull apart things they think might be useless.
The good will has been burned on the “trust me, the government knows best”, so now we’re in an era of cuts that will absolutely go too far and cause damage.
Your post mentioning “imagined inefficiencies” is a shining example of the issue of why they are there. Thinking the government doesn’t have inefficiencies is as dumb as thinking it’s pointless. Politicians are about as corrupt of a group as you can get and budget bills are filled with so much excess waste it’s literally called “pork”.
