He's right about everything in this video, but he leaves out another important detail... Much of the money these institutional investors have to work with was placed onto their balance sheets by central banks around the world, including our own Federal Reserve. The money in your mutual fund portfolios is nice, but that Fed money is really, really nice.
So as bad as he lays it out here, it's even worse. Financial institutions can't do this without the aid of world governments. But what these financial institutions can do is make sure the right people are in positions of power in those world governments.
