In Mexico they are attempting to pay their employees in Walmart gift cards. It won't be long before they pay their employees in canned food and stale bread.
They have done that for a long time. There are many advantages to this, as Walmart is a large enough company with a large enough retail product base to provide a large portion of their own employees' needs. Rarely did my wife ever leave with a paycheck, as when she worked there, an employee could pick up their check and cash it right there, then she would go shopping. It closes the loop on a great many things, removing some taxation from the benefit in the same way that other major corporations can offer an employee discount, such as Ford's A plan. Bitcoin would be a huge boon for Wal-Mart, if they were willing to accept it against the wishes of states; but would be a bigger boon for Bitcoin. The amount of money that crosses from the US into Mexico due to families sending money to other family members is huge, and quite a source of funds for Wal-Mart as it is. If they started accepting bitcoin in exchange for store credit, as well as selling bitcoin at the money services desk, they could completely cut the banks out of the loop.
The bankers won't be happy, though.
