It will be pure speculation/imagination and no-one will able to confirm/deny the bias. Hence the question is fluff. It's like asking a highly imaginative question and trying to translate it to real world. It's nothing more than luring into something which will never happen. It's not bad that you think about these things, but don't waste your time with it.

"Most successful people would become successful irrespective of starting conditions." - again bias and imagination/speculation. Success is not something you are born with. You "get" it. Just because you got it once doesn't mean you are entitled to it for the rest of your life. Successful people getting more success have much more means to become more successful so it looks like they would have been successful anyway.
