True, I have been saying for a while now that Hkers can easily solve their housing AND their jobless problem if only they are willing to live across the border. But China can encourage them if China make the border crossing free of hassle for Hkers. In fact, why not just get rid of the border, and unify HK and Macau immigration with Mainland one so foreigners also only need to check in once if they come through HK or Macau into ML.
