How many government employees must we lay off to actually boost employment?

In the Alice in Wonderland world where down is up and everything works in fun-house mirror ways, we know that cutting taxes always brings in more tax revenue, deregulating banks and energy companies like Enron produces good corporate citizenship, and we have people working for the government telling us government can’t possibly create jobs; slashing government will always produce magic jobs that instantly spring up to replace the fake jobs that were cut.

So must we lay off all 4,377,777 Government employees to increase employment, or would just a million or two out of work give enough boost to do the trick?
