The capital in RenTech's flagship fund is 100% from the employees of Rentech. These guys are managing their own money. So the idea they're screwing customers on it is false, they are the customer. I think they have some other funds as well, but not the flagship Medallion fund.

I did IT at a Wall Street investment bank. Jim Simons and these math and CS guys at Ren Tech made a paradise for math and CS people over there. At investment banks you make money for heirs, and as IT are treated like garbage, and their IT and quant operations are garbage at investment banks (relative to hedge funds). Rentech, DE Shaw etc. did quant math, IT infrastructure etc. right and are kicking investment banks ass. Rentech manages employee capital instead of handing it to heirs and underpaying IT and treating IT like shit and having a shitty IT infrastructure like even the top investment banks often do. So these hedge funds are demonized by traditional Wall Street, who are trying to hang some populist halo around the criticism. It would have to be a populist or liberal/soc-dem criticism, because it's certainly not some kind of Marxian criticism. Marx explained how exploitation happened in capitalism, and it's not by a bunch of machine learning gurus managing their own money figuring out how to trade commodities better than Wall Street investment banks who manage the money of heirs.
