I agree. There is still plenty of fraud in those markets post rule change. Lots of the "pink current" stocks are obviously fraudulent - just because someone can make up unaudited "financial statements" (or entire management teams) out of whole cloth doesn't make it on the level. People will still be running pump and dumps on the gray market crap (but it probably won't be as lucrative). Gensler wants more attention paid to Crowdfunding and Reg A fraud, so they will need more people for that. And SEC registrants are not immune from fraud either, though it tends to be a different kind of fraud from the dead, dark and "alternative reporting" company types.
And even if the SEC didn't desperately need trained personnel, I know FINRA will be hiring for their expanded oversight responsibilities, too.
