Walker - and tax revenues are actually larger when marginal tax rates are lower!!!! History proves this. Do we tax so everyone can pay their 'fair share' or do we tax to raise revenue for the federal government to spend?
When you change the tax rates you change the behaviors of the tax payers. This is particularly true of tax payers who can afford to have tax accounts. We have an entire industry in this country devoted to helping people minimize the amount of taxes they pay.
