Amity Shlaes is in full-throated opposition to the mortgage interest deduction, here:
The distortion of the housing market, we now know, stemmed not only from the tax deduction but also from the subsidies of government-sponsored entities such as Fannie Mae and Freddie Mac (FMCC) and from inappropriately loose monetary policy promulgated by the Federal Reserve. ...
Opponents of deduction abolition today argue that abolition will make the market crash some more, as per Thomas of the Realtors. One could argue this the other way. Now Americans see houses for what they really are: boxes that depreciate. This is therefore the least expensive time to abolish the deduction. We have already taken the hit -- and 2012 is also the time when we most need the $100 billion or so from the elimination.
No mention here of the cost of, say, the reduced rates of taxation on capital gains and dividends, which came to $91 billion last year. Nor of the costs of any of the other tax loss expenditures which benefit everyone.
She's worried about the distorting effects of the deduction on house prices, but fails to address the distorting effects on stock prices of the lower capital gains tax rate. All tax loss expenditures have distorting effects, not just the one for housing.
Worse to me is her objectification of the home as a depreciating box. The fact is housing was long stable in America, until Republicans in league with Bill Clinton started fiddling with it and the tax law surrounding it in 1996. What they did was turn the home into a commodity, which abnormally shot up in value and now has shot down.
The question going forward isn't whether to gut the home some more by removing the tax deduction. Even with it home values have declined dramatically today, and could go even lower despite it as they have in the past. And they probably should and probably will decline without any change to the tax deductibility of mortgage interest. If you aren't old enough to have experienced the housing crash of 1980, you aren't old enough to really understand how relatively small changes in housing values compared to now felt a lot bigger from time to time.
When you attack housing you don't just hurt people where they live in the economic sense, but you hurt them also spiritually. The home in America has been much more than a mere store of economic value, a treasury which greedy government enticed Americans to unleash in a torrent from 1997. The home is the incubator of the next generation of Americans, the place where we engage in the most important work we do as a people: replacing ourselves.
The question is what are we going to do about all the distorting effects of government tax policy, not just the distorting effects of one of them.
That Amity Shlaes leaves them all out except as they impact homeowners suggests not just an economic hostility to housing, but a cultural one, part of a broader hostility which has resulted in family dissolution, not family formation.
If the profane bottom line is tax revenue, the way to achieve it is through more taxpayers. You know the kind: the ones who get up everyday, get to work on time, and work hard.
And the most reliable way we have found to produce them is in families, families which overwhelming still prefer to live in houses.
Subsidizing this enterprise comes with a cost.
So does not subsidizing it.
