You'd be best off watching 'America: From Freedom to Fascism' a forthcoming film by Aaron Russo:
http://www.freedomtofascism.comAll about the IRS tax swindle and the IRS, in that there is no law for the average American to pay a tax on their earnings. VERY interesting viewing. Released July 28th.
Not sure if it will ever get a release here in the UK but for all you American folk, you should be up in arms about this.
