I think that's a comforting lie people like to tell themselves. Lots of hard-working people never get their due. In reality, people who escape bad circumstances often just get lucky. That's hard to accept, because nobody "deserves" to get lucky. We want to believe we earned what we have, and that, if we had to do it all over again, we'd still end up succeeding. But often that's not true.
I think it's more comforting to think that you could've done nothing about your life being bad. It's so obvious that you need both good luck and hard work.
