It's highly recommended reading and the articles he mentions would make excelllent choices for your end of term presentations.
The following excerpt particularly struck me:
Problem #3: The deduction is wildly regressive. The tax savings for households earning more than $250,000 is 10 times the tax savings for households earning between $40,000 and $75,000 per year, according to recent research by James Poterba and Todd Sinai.
If there ever was a case for small-government egalitarianism, then this is it. Eliminating the home mortgage deduction and replacing it with an across-the-board tax cut would equalize after-tax incomes without a single new government program.
Professor Glaeser's short essay does not even address the issue of regressivity relative to our VITA site clients, whose income is typically well below $40,000. Many of our homeowner clients get zero tax benefit value from their home mortgage interest deductions.
I believe the research Prof. Glaeser cites may be this August 2008 article by Poterba and Sinai, Income Tax Provisions Affecting Owner Occupied Housing: Revenue Costs and Incentive Effects. The Poterba Sinai article would make an excellent choice for your end of term presentation. I would be happy to discuss it with you if you are interested in the topic.
