As a public finance economist, Daniel Gross rates an "F", or at best, a "D". He never asks the question: should the Federal government subsidize home ownership? If the answer is yes, he never explains why this is a good policy. Now let's assume, it is good policy, is lowering the cost by subsidizing the interest rate on home mortgages; i.e., through the roles of Fanne Mae and Freddie Mac and the only non-business interest payments individuals can still deduct from their Federal income tax: the interest on home mortgages.
The policy of subsidizing single family mortgages has had a role in producing urban sprawl and the resulting degradation of the environment through destruction of wetlands, larger homes on larger lots, longer commutes by driver-only vehicles, and other causes.
Perhaps the only real beneficiaries of the subsidization of mortgages are owners of vacant land on the periphery of metropolitan areas, and home builders who earn higher than normal profits by building larger houses with more "bells and whistles."
