In Ontario they have a 15% sales tax and high marginal income tax rates. A girlfriend's father, of modest income (something like $50K USD), was in the 50% bracket. Pass the fair tax, and we can be just like our brothers in Kanuckistan.
The FairTax HR25 and S25 eliminate the income tax, abolish the IRS and call for repealing the 16th amendment. There will be only a consumption tax, no income tax. The Marxist/socialist income tax and Gestapo IRS will be eliminated and replaced with a voluntary free-market orientated consumption tax.
BTW, please don't bastardize the language by abusing words like "voluntary" and "free-market". There's no such thing as a "free-market tax"; tax is by definition compulsory, and the free market is by definition non-compulsory. And income tax is just as "voluntary": you're free to have zero income, and hence avoid the tax.
