A criticism levelled against immigration into Britain, unfairly, is that they are only here for the benefits package that they can obtain.
But in America, there is no such protection, so it should be presumed that most, if not all of the migrants are there to work. Mostly in areas of the economy that the white American population will not work.
Also, if Trump is going to deport/jail 3 million migrants, what about the people that are employing the majority them now ? Is he going to jail them as well.
Still can't see "unfettered" anywhere though !
