Even the Wall Street Journal
reported the "supply side economics free lunch" of tax cuts as a means of increasing government revenues effectively dead back in 2003. After George W. Bush cut taxes, the conservative-leaning Congressional Budget Director, Douglas Holtz-Eakin, couldn't come up with figures showing tax revenues increasing in the wake of the tax cuts. If the goal - as initially stated - was to fight the projected surplus in government solvency, it worked brilliantly.
That argument is over - at least among normal folks who aren't on ideological crack. But the persistent argument remains that cutting taxes for corporations generates essential capital that will be directed to creating new jobs - that increasing corporate profitability inevitably leads to a robust, growing economy and employment for just about anyone willing to work.
There certainly may be particular, targeted scenarios - such as cuts in employer payroll taxes or credits tied to new employment - where the desired effect of job-creation can be enhanced by tax breaks, but overall evidence for a rebound of corporate profitability as the magic bullet that will get us out of a deep jobs slump appears slim to non-existent.
