Although I don't think this case is about hiking fees on individual traders, I do think there is a great amount of collusion between the exchanges and the HFT outfits, who gets prior access to the feeds over individual traders. Needless to say, the exchanges receive a hefty kickback for this, which likely far outweighs what they would receive by raising a small fee on individuals.
Yet all we hear from wingnuts is about the federal gubmint has too many regulations blah, blah. So we got monopolies everywhere you turn getting bigger and bigger.
