I was wondering too. But here in US the equation is bit different. The CC networks have already backed the cost of magstripe fraud in the business model. They convinced Americans to pay an elevated fee to balance the inevitable fraud induced by magstripe. Now, with EMV in theory the fees should drop as there is less fraud than with magstripe. Having magstripe around is a way to justify the fees. That is my understanding that it would be difficult now to explain to Americans that they paid elevated fees for so long to pay for fraud that was no fault on their own.
