All this talk of regulating Google, Facebook, Twitter. What about Visa and Mastercard? How is acceptable for so much power to rest in the hands of such a small number of companies?
The problem is that as far as pricing is concerned, regulating at the interchange level isn't going to have the effect people want. That's what happened with the Durbin Amendment.. it capped regulated debit at 0.05% and 22 cents at the interchange level... but processors can still add whatever fees they want on top of that.
