Let's do a little experiment about the Federal Reserve...
 

If you have a few minutes, please read the following court case:

I am curious to see what kind of conclusions you come to after reading this. Thanks.

Congress hard at work for you people again. They get their cake and eat it too, then claim it wasn't cake at all, but rather a sweet tart, which happens to be exempt. ;)

Most of the cases in which a Federal Reserve Bank has been found to be an
agency of the United States concern the tax-exempt status of the Federal Reserve
Banks. Scott asserts that this status, as a tax-exempt federal instrumentality, makes
the Bank a federal agency. This argument is diminished by the fact that Congress
codified this tax-exempt status without any statement that the Federal Reserve Banks
are federal agencies. 12 U.S.C. § 531 (exempting Federal Reserve Banks from
federal, state, and local taxes except real estate taxes without referring to banks as
federal agents)

Did you stop there or something?

It gets better...
