I don't get the hate for billionaires, but the two statements are not logically equivalent. A statement implied by the GP comment would be:
"Every person who ever created a successful company and retained ownership of a lot of it, causing them to become a billionaire, is a policy failure".
Presumably the GP only has a problem with that process when it results in someone becoming a billionaire. My guess is that they think people will still found successful companies even if it doesn't result in billionaires, or that the benefits from successful companies will come about some other way.
