Why? Is there some code of conduct for public companies but not private ones?
No but there’s a difference between private companies and PE owned companies. PE model is very different from regular private companies, and it often involves extracting maximum profits at the expense of the company itself.
And as far as public companies go, shareholders will have to say something about the operation of the company if you start intentionally sinking it.
How does a PE company make money from that - unless who they sell it to is not saavu enough to realize it?
Not all PEs model. The ones you are referring to are often buying large businesses (like the infamous Toys R Us) load them with debt and strip their assets. 90% of the other PEs out there do not do this...in fact the opposite. They put capital on their balance sheet to grow.
There's a pattern of behavior, to be sure. The primary control on public companies is shareholder scrutiny. Gutting your company for short term gains, is not always popular. The more diverse the shareholder cohort, the less popular it tends to be.
Private companies don't mind it when they can literally start a new company with the assets from the old without the pesky plebian investors.
Ofc you know this.
Berkshire Hathaway is a PE fund with permanent capital.
Broadly speaking, making generalisatios about PE is almost impossible because it's an asset class which is, essentially, all non-public business. Instead, it's more useful to think about which element private equity touches you're specifically complaining about: capitalism in general, financial transparency, leverage and liability.
The quiet ones that simply run business well, don't make the news.
There are PE firms that specialize in rescuing distressed companies with potential and turning them around. In many cases not firing anyone and holding onto the form they acquired for a long time.
And don’t call themselves PE. They’re a diversified family business. Or a VC fund. Or whatever the fuck the Ellison’s are doing to Paramount.
It's more about Private Equity firms than private companies. The oversimplified TL;DR strategy for most PE firms is acquire, strip, pump, then dump (combined with all sorts of tax strategies). Most PE firms don't own the companies themselves, but act on behalf of investors and take a cut of the ultimate profits. So it's basically tons of short term thinking.
