When your business model is "we can do this better than others -maxxed" your assumption is there will always be another sucker. 30 years of taking dumps and selling trash has others learning caution and not willing to buy on a hope and a dream. Suddenly when the suckers dry up business is challenging? You have no model.

Data point; I've only had 2-3 PE job conversations in the last 15 years and have had 2 in the last 2 months as I explore the market and both mention that the management Equity are "looking to exit" in the next 18 months. Everyone looking to be a "PE expert" type company and everyone forgetting we actually need companies run for the long-term; ratio of "experts" to actual doers is definitely too high.

Its almost like they bought the companies to kill competition, and the only ones shouldering the loss are the lowest paid workers.

As long as there's capitalism, there'll be capitalists. I get poo-pooed almost every time I say this, but you'll never convince me the words capitalism and capitalize - meaning "to take advantage of" - are unrelated. Yeah, the inevitable massive recession/depression that is coming will cause some regulation to happen, but those behind it will do their damnedest to keep it as minimal as possible so they can pull their shit again, followed by gradual perversion of any regs they can't prevent from the get-go.

EDIT:
TL;DR: They may dig their graves, but - like the undead - they'll be back to suck the life out of the living.

It's not income inequality, because for tax purposes most billionaires don't take an income. It's wealth inequality.

Mostly spot on. I'd add that a lot of pensions and 401ks are wrapped up in private equity/credit as they've been showing good returns (on paper at least). I'm rooting for their demise but expect if/when they take a big hit, it won't just be billionaires hurt
