My "hot take" if you will:

SEC and FDIC aren't usually, to the general public, negatively seen due to their mission. Its the fact they don't prevent criminal / unethical behaviors beforehand, and banks get away with alot before anyone intervenes.

I actually don't think the average US citizen is "anti regulation" with this. I think - and I include myself in this - that we see agencies like the SEC (more so than the FDIC) don't act fast enough or often enough, and when they do, the fines are a slap on the wrist vs the profit made by the bad behavior.

In a nutshell, they just aren't acting effectively, and thats why they get a bad wrap.
