Life expectancy is dropping like a rock, and that's a number with a little more rigor behind it than PG's moronic hand waving. The guy has no idea what he's talking about and comes across as incredibly desperate to justify obscene hoarding of wealth. He'll draw a line between any two data points you can dig up, no matter how distant and spuriously correlated, if it will allow him to fellate a few billionaires.
We get it, these people pay you. Just say it: "I can see nothing wrong with the current distribution of wealth because the lenses in my eyeglasses are actually solid gold, a gift bequeathed to me by the Duchess of Facebook." The guy needs meritocracy to not be a myth, because he's styled himself as some kind of kingmaker who can selectively pluck only the most deserving young founders from a bubbling vat of Stanford alumni DNA. It's been a good run, but it's just getting gross now.
