Well if I understand it correctly, this will actually lead to less revenue for the U.S. Government. They are not instituting a federal Internet sales tax--they are forcing merchants to collect sales tax that is due to the individual state in which the purchaser resides. Aside from the problems this will cause for smaller businesses on the Internet, this will increase the Federal deduction that individuals can claim due to payment of state taxes. Higher federal deductions == less money for the feds (though almost certainly more for the individual states.)
Hey you! Don't you use that logic stuff here! On Slashdot, we don't take kindly to people who use logic.
I'm a Lisp variable -- bind me!
