They're doing NOBODY any favors. They haven't removed one thin dime of tax liability from anyone's back.
If we had a flat tax or a consumption tax, then all tax payers would be equal.
Tax payers are never equal unless they pay a pure Capitation or head tax. Try and collect that from a person without the dollars to pay.
All other systems rely on some action or event that the taxpayer must engage in, and is taxed to the degree he engages in that action. Since different persons engage in taxable events to variable degrees no to person can ever be said to be equal in paying a tax. That is why the rule of uniformity for indirect taxes is geographic(i.e. the same law wherever you may be), but does and cannot require equality between individuals.
What ever happened to equal protection under the law?
Everyone is subject to the same federal law regardless of where they are in the United States.
