Nationality and the rental market :: Khaleej Times

Landlords believe that some nationalities make better tenants than others. They also believe that many persons prefer living in neighborhoods with others of their nationality.

This has always been so. Yet the article was given the headline "Now, landlords turn choosy on tenants nationality." Perhaps that's because discrimination has become cheaper to exercise now that government rent controls have been put in place, creating an apartment shortage. When there's a line waiting for your services, and you can't raise the price, then you can afford to be choosy.
