I am not confused, and I don't think we are necessarily disagreeing. My point isn't that billionaires are faultless or good. My point is that they are not the root of the evil. We cannot just rid ourselves of the billionaires, pat ourselves on the back and call it a day. We have to do that, and then go further. We have to, at the very least, put the guardrails back in place to ensure a new crop doesn't pop right back up.
The great crash and the following great depression took care of the robber barons. We regulated in order to avoid them again, but eventually forgot our lesson. I suspect that the AI crash will take care of this current batch of rich fucks, and we will once again regulate and focus on people like FDR did. I just wish we would stop forgetting the lessons of the not so distant past.
