Asset management has traditionally been a great business, and BlackRock (BLK) is perhaps the best. In fact, most companies based around Wall St. (both industry and geographically), have done historically well at making their investors money.
Wall St. has always been a step ahead of the main street in the financial sector. They are the deal makers and while they don't control the prices of assets per se, they have an inordinate amount of influence, so the net result is similarly advantageous.
Now obviously, no one writing on Seeking Alpha has anything but admiration for "The Street," because without it this website would never have been invented, but I just wanted to give context to my thesis.
