Two out of every three United States corporations paid no federal income taxes from 1998 through 2005, according to a report released Tuesday by the Government Accountability Office, the investigative arm of Congress.
The study, which is likely to add to a growing debate among politicians and policy experts over the contribution of businesses to Treasury coffers, did not identify the corporations or analyze why they had paid no taxes. It also did not say whether they had been operating properly within the tax code or illegally evading it.
The study covers 1.3 million corporations of all sizes, most of them small, with a collective $2.5 trillion in sales. It includes foreign corporations that do business in the United States.

The only state interference in the economy "the market" is really against is, the use of the people's own "public wealth" to rescue and serve the interests of the working class and its poor. For huge, rip-off, so-called "free market" capitalists, it's a different matter however, even for foreign one's of the US Empire-, indeed them especially.
These particular tax exemptions and other corporate welfare rip-offs going to the benefit of US Corporations, as well as our own, is simply a continuation of this Grand Tradition of we, the public, bailing out and welfare hand outs that go to allow the excesses and "free market" Grand Theft traditions of capitalism.
The Free Market is really such a fine tuned and performing piece of capitalism's self-regulation isn't it?
"Just get the state out of its way, and let it create wealth and make us all rich."
In a pig's goddamn eye!
Spot on! Work hard and prosper is a pleasant fiction, designed for the rubes. Look what good "Arbeit Macht Frei" did for the concentration camp inmates! Were there any truth at all to this fable about hard work, the illegal drug business would wither and die on the vine (to cite but a single example).
