Don't kid yourself. There's a wide gulf between a worldview based on a few anecdotal successes and the more realistic picture emerging from a flood of statistics, which not only show the rarity of mobility, but indicate that it's declining - esp. for those unfortunate enough to be born at the bottom.

Yes, people can win Olympic Gold (we're not competing against robots yet), but very few will and those who do will have to make extraordinary sacrifices. So yes, give them credit. But don't - whatever you do - look at people who haven't managed to keep their heads about water, and think "well, this one guy made it against all odds and you didn't, so you must be a lazy, stupid human."

That may be fair (if harsh) in a supportive world where it takes rare talent to fail. But it's a monstrous attitude in a world where the opposite is so clearly the case.
