You are right. Bill Gates got his start up capital from his father-in-law. And yes, others would not have had the same unique opportunity he was presented with. Welcome to the World, please let me know how you intend to fix the fact that we all have a unique set of circumstances.
Maybe i'm misunderstanding you. please let me know.
Yes, you are. That observation was offered as a rebuttal to the fatuous nonsense that "anyone" can achieve great success in this country. It has no other significance. It does not present, in itself, a problem to be solved, or a wrong to be righted.
On the other hand, it does do a nice job of undermining a really stupid argument against doing something about the income inequality which, in general (as opposed to this particular item in specific) DOES present a problem that can be solved, or at least ameliorated.
