Rather than the system we have now, I would rather have a national sales tax of 5%, which excludes food (meaning potatoes, meat, eggs, milk, etc. and not packaged poison like chips, dip, ice cream, etc.), medicine/medical care/medical supplies, clothes (up to $200 per item/pair/set), housing (rent/mortgage), and finally all firearms, ammo, and accessories. 

Everything else: 10%. 

Every 5 years, the tax rate would be reviewed and can only be adjusted down if the national debt increases, as a small, direct protection against inflation and may never be increased, as if any other national tax is levied, the system has a self-destruct clause which will nuke the whole thing. 

This system is easy, more fair and equitable since everyone will contribute, even illegals or tourists, it spares "the poor" from paying taxes on actual necessities, and encourages citizens to become more self sufficient.  

 I agree in principle.  I'd probably make a few very minor tweaks, but I am 100% for eliminating all taxes except a sales tax and making every receipt show how much we are paying to each taxing authority.  People need a reminder of how much they are actually paying.  When they are nickel and dimed to death by a 100 different taxes, they have no idea how much they are actually paying.  Many taxes cost more to comply with or to enforce than the revenue they bring in to the government.  It is such a waste. 

 I like the tax accountability part!
