Obama what a nit wit we have for president...First off all you would have to do is tax western Union when purchased for foreign countries. You could do the same with money orders that would only be good in the USA and another one taxed for foreign countries...prepaid debit card the same tax or a fee for use in foreign country. How hard would that be to do? Any money being sent out of the country could be taxed when purchased. At least we would be getting something back into our economy. Instead of Mexico having the benefit of untaxed money boosting their economy.
