Free-market economic theory suggests that the American real estate market should not have been able to exist as it has for decades.
Americans have long paid unusually high commissions to real estate agents.
Some real estate brokers, recognizing the chance to win business by charging lower commissions, would have done so.
Instead, an average home sale in the U.S. has cost between $5,000 and $15,000 more than it would have without the inflated commissions.
This money has been akin to a tax, collected by real estate agents instead of the government.
