I would contend the National Debt is really meaningless. Everyone carries debt, debt isnt always a bad thing. Only one president in US History has ever payed off the National Debt and no president will ever do it again. Americans are overtaxed and thats a fact, overtaxed by a questionable tax system in the first place. Get rid of the IRS and put in a national sales tax. So its ok the Clinton lied to a grand jury? Ok, if you ever get called for a grand jury and lie what are they going to do to you? Let you go free and clear? Doubtful. Perjury is criminal whether its lying about a blowjob or lying about murder. I bet you'd be the first the crucify Nixon though. I remember Travelgate, Whitewater, Filegate, Vince Foster and on and on. Bush didnt lie about Iraq, he stated what he believed, Kerry agreed with Bush before the start of the war. Sadam did have WMD and they are probably still in Iraq or in Syria. Anyone that says their are no WMD are lying to themselves and to the Americans. Some of those weapons they had that killed thousands you can fit into a tube that you can put in your pocket. So whats not to say they weren't snuck out or buried? What about all the weapons the US Soldiers have found buried since the war? They wouldnt bury the WMD which would be the most damning evidence against them? Just for example. Have the Europeans ever found all the art work and gold the Nazis hid in the Second World War?
Re: National Debt: National debt may or may not be meaningless; however, long-term budget deficits drag down the economy.
You say that it is a fact that Americans are overtaxed. Do you have any evidence for this supposed fact? Here's some that disputes your claim:
Total tax as percent of GDP:
United States- 28.9
Japan- 28.4
Germany- 37.0
United Kingdom- 37.2
Canada- 37.4
Italy- 42.7
France- 45.2
Sweden- 52.0
As you can see, among the top 8 industrialized countries in the world, only the citizens of Japan (barely) have a lower tax burden. Replacing our progressive income tax system with a national sales tax would shift the tax burden to the lower, working, and middle classes. If you want to destroy the middle class, then a national sales tax is a great idea. Without the middle class, there would be noone to buy all the fancy products that corporations produce, so a national sales tax would eventually hurt business and the upper classes, too.
Taxes pay for social services on which many lower-income people depend. Perhaps you make enough money that you don't need many of these services, but to rob these programs from those Americans who do need them so that you can pay lower taxes is just plain selfish.
