You don't need an IRS with a flat consumption based tax......better known as a national sales tax.
The EPA is purely an advocacy group for tree-huggers.....nothing more. They hold up progress and do nothing to clean up the planet....and especially have no effect on global climate change. It's a scam.
Aside from the national sales tax being a fantasy, exactly what would the tax on everything be to cover the annual budget? 10%? 20%? 35%? Would there be an extra tax to pay off the National Debt?
And the EPA is a regulatory agency, not a advocacy group. The EPA enforces clean ups. They are the ones that made big oil clean up the gulf spill. Without them the whole Gulf of Mexico would be dead by now. Houston, New Orleans, Tampa Bay and all the rest of the cities on the gulf would be totally bankrupt. Property values in Santa Barbara would be junk. Valdeez Alaska would not be a fishing port any more. It's only a matter of time before nuclear waste is the next monster clean up. You should go try living at Chernobyl, or Three Mile Island.
