Historians and economists who've studied the 1930s conclude that the tax increases passed during that decade derailed the recovery and slowed the decline in unemployment. That was true of the 1935 tax on corporate earnings and of the 1937 introduction of the payroll tax. Japan did the same destructive thing by raising its value-added tax rate in 1997.
The current outlook for an economic recovery remains precarious. Although the stimulus package will give a temporary boost to growth in the current quarter, it will not be enough to offset the combined effect of lower consumer spending, the decline in residential construction, the weakness of exports, the limited availability of bank credit and the downward spiral of house prices. A sustained economic upturn is far from a sure thing. This is no time for tax increases that will reduce spending by households and businesses.
