There is a rarely mentioned coincidence of interests here between economic conservatives and multicultural progressives. The former love the fact that additional immigration increases the number of unemployed, boosts the supply of  labour, keeping wages relatively low or even reducing them, thus bolstering the bottom line. "Progressives," on the other hand, not only get to increase the "diversity" that is the ultimate goal of their multicultural fantasy religion, they also get an appreciative bloc of voters, jobs for immigration lawyers, human rights advocates, social service workers, civil servants, and a whole slew of other well paid jobs that keep them all working. None of this is altruism people. It's cynical self interest masquerading as humanitarianism.
