I wonder who would prosecute them. What about an AG who, when confronted about doing a bad job, deflects by pointing out that Nasdaq is "smashing records?"

I'd be in favor of giving Lina Khan a lifetime appointment to heading the FTC along with 10x their current budget to tackle exactly this problem.

A major part of the problem isn't even that we don't have laws on the books, it's that funding to the enforcement agencies has been gutted to the point where they can mostly just go after extreme egregious violations or very easy to win cases. The IRS is in exactly the same boat.
