Most of the cleaning service people are not really taxpayers[1], which is why including them distorts the equation. They are benefiting w/out contributing, and we do in fact, need them. Also reinforcing my point, How can you claim that Defense is the only public good in the top 5? What percentage of the population must benefit to qualify? [1]From other IRS data, we can see that in 2008, around 52 million tax returns were filed with either positive or negative AGI that used exemptions, deductions and tax credits to completely wipe out their federal income tax liability. Not only did they get back every dollar that the federal government withheld from their paychecks during 2008, but some even received more back from the IRS.
