Apparently the countries of origin have to AGREE to take these folks back into the country. So if that is true why is Mexico agreeing to take back all those folks and what other destination countries are there? Is is just Mexicans we want to get rid of or ALL UNDOCUMENTED WORKERS? Inquiring minds wanna know these things. Will all 11 million undocumented workers eventually be booted? At what cost? How many zillions of dollars and will that cost be offset by increased taxes on the wealthy?
