51.2% of Americans are Government Dependent.

Recent Reports state that 35% of the wages collected in the United States are government benefits. This does not include local, state and federal workers.

The Math: August 2009 numbers

Federal workforce: 2,823,777

State & Local workforce: 19,808,604

labor force Aug 2009 154,577,000  employed 139,649,000

16.2% of workers work for the government.

Total government dependency is therefor approximately 51.2% of Americans.

Yes, these numbers are not apples to apples, but there is a reason such numbers are not available.
