The problem is that the real estate brokers' lobby in the states is pretty powerful, and they have a stranglehold on the MLS. They've lost a couple of anti-trust lawsuits requiring them to provide MLS information to other companies, such as zillow, but with caveats that make the information almost useless (60 day delay providing new listings, limited sales information, etc.) Unfortunately, MLS is the most comprehensive source of local properties for sale, lease, and sold. As long as the brokers and their buddies that regulate them are the gatekeepers to that information expect agents to still be around sucking up 6% commissions.
