This is just wrong. VC is not PE. The Vet example is really a bad trope. For every bad deal there are many others you never hear about. PE firms are not making money by simply buying everything up. The business still has to maintain and grow.

VC is most definitely a form of Private Equity, though it's not the limited-partnership deal model that we often see in SaaS, or Vet Clinics, or Housing, etc. Yes, they need to grow but PE firms don't invest directly. They have funds with relatively short time horizons that want 2 things: 1. cashflow during the fund lifetime and 2. equity growth so they can sell the assets in the fund prior to the end. PE firms will sometime flip portfolio companies to their next fund but this is frowned upon because the investors are sophisticated and recognize the valuation conflict of interest. The PE business depends on repeat business for selling their funds; the best are always over subscribed and never go shopping for investors, while the rest are marginal forever.

Sure there are differences between tigers and vultures, but they both eat things till they're dead.
