I am surprised others missed what's happening here. Bitcoin is only in the hands of privileged people right now. Imagine the people in the world that will never own bitcoins because they're simple too expensive, or they're not writing software, or they live out in a desert.
He didn't say they should be out of the hands of the ordinary, just that they are. It's inequality 101. Not much you can do about it, but still amazing people here misunderstand.
If there is a "problem", it's not remotely to do with Bitcoin.
Bitcoin is merely an expression of existing wealth, modulated by an individual's particular amount of foresight. If you already have (some small amount of) wealth, you can acquire Bitcoin. So it is with any investment.
As far as redistribution of wealth goes, I actually think Bitcoin has done something pretty freakin' awesome. Basement dwelling computer nerds, anarchists, libertarians, supporters of a lot of freedom related movements - all these people had the foresight to get into Bitcoin early, while typical power loving conservative types did not. It may not fit the giving food to starving Ethiopians kind of worldview, but it's still a VERY interesting redistribution of wealth.
Those people who believe in freedom, free trade, efficient money, are buying Bitcoins and will benefit. It may not mean free ice creams for all of Africa, but it's still good.

That's just silly
or they live out in a desert.
Many people in third world places have access to mobile phones. Bitcoin can be a boon to them. See recent news. It's far more likely to become a daily real world currency in places like that than in the richer countries. Maybe they'll benefit when the richer countries do get on board.
