What can be done? Build more housing I guess, but who's to say the most desirable still won't be bought by those looking to pay the most? Not to be dismissive of the impact to those who have up to this point been able to afford it and now must change their lives.. but I don't know if there's any 'cure' for people wanting to sell a scarce resource to the highest bidder.
