The 1960s and 1980s were periods of record sustained high growth, mainly due to the tax cuts and reforms enacted at the beginning of each decade by Kennedy and Reagan, respectively.
The JFK administration, against the advice of many economic advisers, began cutting taxes in 1962, starting with businesses. An investment tax credit encouraged investment and changes in depreciation costs lowered the cost of capital for businesses. The top corporate rate fell from 52 to 48 percent, and the top individual marginal tax rate fell from 90 to 70 percent. The empirical evidence shows that these tax cuts stimulated growth:
The 1980s was another decade marked by sustained economic growth, which was especially remarkable given the stagflation that was strangling the economy by the end of President CarterÂ’s term. From the trough of the recession in 1982 to the peak in 1990, it was the longest peacetime expansion in history.
ReaganÂ’s tax cuts spurred an investment boom, just like in the 1960s after the JFK tax cuts. The Economic Recovery Tax Act of 1981 featured a 25 percent across-the-board tax cut. The tax reforms increased incentives to save, work and invest, which increased the productive output of the economy to match the increase in demand.
