Before looking at taxation under Reagan, we must note that spending is the better indicator of the size of the government. If government cuts taxes, but not spending, it still gets the money from somewhere—either by borrowing or inflating. Either method robs the productive sector. Although spending is the better indicator, it is not complete, because it ignores other ways in which the government deprives producers of wealth. For instance, it conceals regulation and trade restrictions, which may require little government outlay.
If we look at government revenues as a percentage of "national income," we find little change from the Carter days, despite heralded "tax cuts." In 1980, revenues were 25.1% of "national income." In the first quarter of 1988 they were 24.7%.
Reagan came into office proposing to cut personal income and business taxes. The Economic Recovery Act was supposed to reduce revenues by $749 billion over five years. But this was quickly reversed with the Tax Equity and Fiscal Responsibility Act of 1982. TEFRA—the largest tax increase in American history—was designed to raise $214.1 billion over five years, and took back many of the business tax savings enacted the year before. It also imposed withholding on interest and dividends, a provision later repealed over the president's objection.
