So 3 million American families sell and move on to better digs (the new houses), and each one of their old houses gets rented out to non-assimilating third-world bodies-for-ballots newcomers, 3-families-to-a-house. These border-hopping scoff-laws will happily make-do, somehow, living that way. After all, they're paying only a fraction of the rent. Unfortunately for the remaining locals they're also cluttering the streets, parks, and all the civic infrastructure with 3 times the traffic. At the same time they're bidding down the local wages a hefty notch since they, with three breadwinners splitting the housing costs, can get by with less.
The locals, whose wages are now stagnant (if they still have a job), can't afford to move on to better digs like the initial wave of former neighbors, the ones who responded to the DemonicRat's graft-financed invasion, but they also don't want to live 3-families-to-a-house. They get fed up with the new non-assimilating third-world bodies-for-ballots neighbors (the DemonicRats latest crop of useful saps), and they now move out to the sticks. There, at what will hopefully be a lower cost, maybe they can keep their one-house-one-family American dream. Or, maybe they'll just surrender to living-the-dream in a trailer. Joy!
What happened to the other one million NATWBFBs you say? They're living the life of professional con-men & criminals. After all, once you own nothing, you'll be happy! The WEF said so.
