Private equity is infecting every aspect of your life and the tactics are the same:
1. Cut costs;
2. Jack up the prices;
3. Block competition by buying them up, legislation/regulation, etc; and
4. Loading the entity up with debt and cash out before it explodes.
No value is being created or added. It's pure wealth extraction. Some cases are essentially state violence (eg buying up mobile home parks). Others are just downright immoral, like exploiting the love people have for their pets here.
