ERIC POSNER: “Home ownership policy of the Bush and Clinton administrations was, in essence, an attempt to pay low-income people to make a risky investment that they would otherwise rationally avoid. I cannot understand why anyone would think that such a policy would be sensible. In some cases, these people will do well and enjoy the upside of their investment, but in other cases they will do poorly, with the result that they will be worse off than ever.”
