What does this mean?
Hedge fund managers are mostly very active in philanthropy.
I think he means that nothing useful is produced by running a hedge fund. You may say "oh but what about the money?". Well, it was not earn (in a usual sense), just taken out of the market, money changed hands, that's it. Nothing was manufactured, produced, researched, invented or serviced in the process. Think about it: if everyone worked in finance industry, who would clean the toilets?
