Problem:
Congress uses the Tax Code to influence our behavior. Examples include deductions for mortgage interest and property taxes to steer people to home ownership instead of renting. Or, tax credits for purchasing products that use alternative energy are another incentive. Likewise, deductions for charitable contributions encourage charitable donations.
Is this a good (i.e., proper) way for Congress to achieve economic objectives?
Can you identify other tax deductions or tax credits that encourage particular behavior?
