I'm not at the retirement age and I was able to continue to run the business, yet sold to PE. How do you explain this?

Also, see my comment below. Feel free to list out all of the companies from those portfolios that match your criteria. I'll wait patiently.

Like I said, I wasn't talking about random B2B startups, and you're going to hit retire age someday. I don't understand what you're arguing against. If we lived in a place that is hostile to "private equity", the majority of the companies you listed never would have been started in the first place.
