"There are two larger points we should not lose sight of," Gayer writes. "First, tax expenditures are not a free lunch. The billions of dollars spent on the tax credit will ultimately have to be paid back through higher, economically distorting taxes.
"Second, government policies to promote homeownership (or, more accurately, home-borrowership) were partial contributors to our housing and credit market problems," he continues. "Ultimately, we need to decrease the government's housing incentives, including the mortgage-finance subsidies, the mortgage-interest deduction, and the favorable capital gains treatment for housing. A good place to start this weaning would be by not extending or expanding the home-buyer tax credit."
That's the view from Brookings, which never has been accused of being a conservative, free-market outfit. But this isn't a question of right or left, just common sense.
