Conservatism.

One thing people miss about the whole "evil, gub'ment public sector" employee with his mitts out for a handout vs. noble private sector worker pulling himself up by his own bootstraps is that when the government can't have it's own employees do a job, that task doesn't simply vanish into thin air, but the government just hires private contractors to do the work.  Which, we're now finding out, actually costs the taxpayer MUCH more money that if the government had just hired the same people as employees in the first place:

POGO estimates the government pays billions more annually in taxpayer dollars to hire contractors than it would to hire federal employees to perform comparable services. Specifically, POGO’s study shows that the federal government approves service contract billing rates—deemed fair and reasonable—that pay contractors 1.83 times more than the government pays federal employees in total compensation, and more than 2 times the total compensation paid in the private sector for comparable services.

How many Republicans would read this and accept okay, the public sector should be way more filled up than it is, ie the opposite of it losing 600,000 jobs since ObamaTheSocialist took office?

Gee. That's a tough one.

In other words, ideology vs. conservatism.  "The Gut!" vs. Brains.  The opposite of pragmatism.
