Too big to fail

Part of the fallout of the last couple of wikiweeks is the sudden realisation that on the internet there are only really two major companies that allow you buy stuff over the internet internationally. They are US companies that have been carefully nurtured by the US government with special agreements in various countries around the world and they are beholden to the US government will do their bidding. I'm talking about Visa and Mastercard.

It seems to me that this is a financial monopoly carefully nurtured by the US.

I don't understand why we don't have some kind of international standard to allow other companies to interoperate to make this kind of money exchange possible for many companies. Isn't about time we started?

I wonder too if these companies are now "too big to fail". Surely by now "too big to fail" is an alarm call. "Too big to fail" equals "too dangerous to safely allow to continue".
