All of this is why the current tax code needs to be abolished and replaced by some form of flat tax system.

"The new flat individual income tax system will be designed so that federal individual income tax receipts will be equal to approximately 8% of the country’s gross domestic product (GDP), in line with the historical share of federal individual income tax revenue relative to the size of the economy 16 The cumulative tax changes proposed, including those to the corporate income tax system, will be designed so that total federal revenues average 18% of GDP, the 50-year U.S. average for federal tax receipts. The federal payroll tax will not be affected by the new flat tax system."
