I beleive that one way to reform the tax code is to get rid of the home mortgage interest deduction. It was meant to encourage home ownership. However, it’s doesn’t do any good because the market simply priced that tax break into the prices of houses.
If the tax deduction were taken away, home prices would drop accordingly and affordability would remain the same.
Generally, the government should get out of micro-managing and let the markets take care of themselves.
