> Because a PE fund is at most a seven year timeline

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 problem with PE is only the hyper aggressive and generally terrible ones make the news.

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.
