There's no income tax, so I keep everything I earn. If I was to decide just to "take it easy", not buy a new car, or a boat, etc--just live a very moderate lifestyle for the year, I'd pay no more in taxes than someone earning $75,000 a year. So under this set of facts, someone who earns $750,000 pays the same amount in taxes as someone who earns 1/10 of that amount. Now I understand the guy who earns $750,000 is likely to spend more money than the $75,000 earner, but there would be a significant incentive for the higher earner not to spend on things subject to a national sales tax, and simply save his money so it's not taxed. The less he spends on purchases, the more he shields his income from taxation. I don't think this would lead to the kind of income system that would work too well. The higher earner could also decide to "buy, buy, buy" everything he needs in one year, and then take a spending hiatus for the next 2 years, which again would mean he wouldn't be paying any more in taxes during the 2 non-spending years than someone earning far less.
The other problem with a national sales tax system is that the amount of revenue into the government would wildly fluctuate depending upon how the economy is performing. Revenue would drop sharply under the kind of economic conditions were are currently experiencing; taxing income provides a more stable and predictable revenue stream. That's why we've been doing what we're doing for so long.
Unfortunately, there are no easy answers.
