@Cycloptichorn,
While I don't argue with some of the remedies proposed here, particularly with respect to equity financing, I believe the graphical picture which appears to be the basis for the central contention involves significant variables not cited or even acknowledged, and that the central conclusion that these tax revenues are at a near all time low due to some presumed structural problems in the tax code, clearly involves some dubious misinterpretation of the data.
In the first place the scale of the chart was carefully selected to include the tail end of the unusually high WWII tax rates. Indeed a careful examination of the chart reveals significant trends that contradict the central thesis of the article.
In the second the authors fail completely to acknowledge the effects of economic variations on tax collections: in some years corporations lose or don't make much money, thereby reducing tax payments. This is what was behind the steep decline in tax payments in 1977-79 and again during the revent 2007-2008 drop.
It is noteworthy that just before the recent recession, corporate tax collections were at their 1970 levels, and that the trend since 1980 has generally been up - a 30 year period of increading corporate taxes as a % of GP.
I offer this merely as an illustration of the deceptions that can result from superficial research and the thoughtless, uncritical consumption of propaganda. There's more to understanding than just finding links to opinion pieces, and more to the truth than just the headline propaganda.
