These three institutions continue to hold major portions of all big stocks in the world. Blackrock and Vanguard hold over 12.5 TRILLION dollars worth of assets. With Blackrock being a key investor in the defense industry and Vanguard being key investor in healthcare, pharmaceutical, insurance & education - ie with collaboration with Harvard (Harvard Vanguard), these two corporations alone pretty much control the world.

It was interesting to see globally acclaimed Vandana Shiva make a speech about these companies and how they are in control of world economies. Highly recommended watch.
