Isn't it ironic that

A) Would that not mean a black market economy? andB)this tax exists already in VAT or whatever it is called in the different countries, of course together with the income tax so not so high that everybody buys 90% of their things on a black market C) this means also that a government will try to let you spend as much as possible?
Would this also count for second hand things? And if so would that mean that the government could make a few times the value of a car made by somebody? And if not would that not make the difference in price between new and second hand things so big that people buy a lot less new things (which is negative for consumerism) How would this work between different countries? If I come from a country with income tax, i would never in my life buy something from a country with pure sales tax.

I like the idea....I am however not sure how to make this work.

Sales taxes suck because they are an extremely regressive form of taxation. Florida tried something called a "Luxury" tax which only applied to things such as Mercedes, Bentleys, Rolls-Royces, yachts, Lamborghinis, Ferrari's, and related items. OMG you've never heard such bitching and moaning in your life... it's not fair that I have to pay for the prvilege of driving a Bentley... the average Joe should pay for it... but not me. Needless to say... it didn't last long. What was it replaced by? A higher sales tax on non-luxury items.

It's an undisputed fact that sales taxes, VAT's, and whatever the hell else people want to call them disporportionately affect lower income folks. Let's say that the total sales tax on necessities for the year comes in at $1,000 (may even be higher in states that also tax food:P). If you're making $20,000 per year that's 5% of your income. If you're making $100,000 per year, that's 1% of your income. If you're Bill Gates you don't give a flying "f" about it. Which probably explains why sales taxes are so popular here.
