"The world at large is less inequitable today than at any time in history. Number of people in abject poverty, as a percentage, is at all-time low. Innovation means it will continue to go down. I do think in most problems time is on our side. Absolutely right there are some big fortunes and it’s not good to have a society where you don’t have mobility between different income levels. Education ought to be good enough to move between them. Maybe self-serving, but I wouldn’t say it’s because a few people are very rich, I’d say it’s because we aren’t doing a good enough job on education."
