My guy, those are called publicly traded companies. This isn’t a new thing, or in some way sinister, it’s just how stocks work. And by the way, vanguard is a passive index fund, they don’t buy stakes in companies and start making changes to the corporate structure, they buy shares in big companies, package them up and sell those packages to investors (normally things like pension funds or the like.) they don’t just own the shares outright, they own them on behalf of other people.
But that’s not the point of OPs post. I won’t say PE can’t be extremely shitty, but that doesn’t mean “everything is a lie!” Like op said, or that “we need more cold blooded murder of innocent people.” Like you said. Most PE firms wind up underperforming anyway, they lose money on doing things like this and people are starting to realize that. If you don’t like things like labor outsourcing we agree, but don’t support psychotic murders because of it.
