The Republican message for 2012 is as irrefutable as  1 + 1 = 2. And Obama threw himself headfirst into the bear trap with his veto of the Keystone project.

One one hand, we have nearly a fourth of working-age Americans without jobs, the worst proportion since the early 1980s. On the other, we have $2 trillion of cash sitting idle on corporate balance sheets, as President Obama complained in a February 2011 speech to the U.S. Chamber of Commerce. We have investors languishing for lack of returns, and unemployed people languishing for lack of work.

Standing in between prospective workers and prospective investors, preventing capital from employing labor, is Barack Obama. Someone really ought to to draw the cartoon: a $2 trillion cash pile gathering cobwebs on one side, an endless line of unemployment on the other, and Barack Obama in the middle, keeping them apart.

Under Obama, the United States has suffered the steepest drop in private investment since data were kept, as well as the slowest recovery.

The flip side of the investment bust is the worst employment-to-population ratio since before the great Reagan recovery:

To put this in perspective, $2 trillion of idle cash represents two years’ worth of American investment in equipment and software. Why would corporations rather earn rounding-error levels of interest at the bank than put their money to work  in profitable ventures?
