The economic engine of refugees

In honor of Labor Day, this is an interesting article that discusses the major economic force represented by refugees and other migrants.  They contribute valuable work to their host country economies and tend to pay more taxes than they use in services.  Most impressive in magnitude is how much money they send back to their origin countries.  There is a whole economic sector that has sprung up around this.  Western Union is the major player, but there are many others taking a chunk out of refugees' and migrants' hard-earned wealth that they send back home.
