While I agree that this is good to see, it doesn't scale at all. How many people can really afford to pay their own rent and bills, and still have enough left over to pay rent and bills for another family? And to play devil's advocate, how does the overall cost (monetary, time, interruption, etc.) of doing this compare to the cost of "fixing" the situation in their home country? Granted it may not be feasible politically, but inviting in a bunch of refugees is a political minefield, too.
