With Weinstein, he was a successful serial abuser because he had both carrot and stick. His power meant he had leverage on everyone around him who might speak out, and his money and connections meant that he could buy silence if that didn't work.

I believe that this happens on a smaller scale with other serial abusers, they seek out situations where they have leverage so it's harder for someone to speak out.

IMO, this kind of pressure only works when a) it's coming from their boss, or b) they're the kind to be motivated by morals.

And, again IMO, if they're motivated by morals, they aren't serial abusers; the reasoning being that once informed that they're crossing the line that isn't acceptable, they stop.

But given the ~1% rate of sociopaths in society at large, I have no problems believing there's a large overlap in the Venn diagram between sociopaths, those in power, and serial abusers.

Oh, don't get me wrong, enabling serial abusers is a huge problem. But nothing we do is going to change the behavior of those specific individuals - it has to be about enabling easier reporting and better follow up. It's a classic bimodal system where you need accountability and support to find and exclude egregious offenders, and systemic engagement and education to prevent first offenses.
