Not only would it discriminate severely against the poor, the only way it COULD make as much money for the government would be to discriminate against the poor.
Consider: There’s no way in hell legislation could get passed that would do away with income tax and place a flat tax on absolutely anything sold. Anti-poverty groups and most everyone would insist that basic needs, like food and shelter, should be exempt. That would cut down considerably on the tax base. I spend approximately 35% of my monthly income on just food and housing. If I get to keep all that I earn, and nothing goes to tax, I could end up spending approximately another 50% of my monthly income on “consumer goods”, including gas etc. If the government was going to suck as much out of me through a sales tax as they do now through income tax, there would have to be approximately a 100% tax on everything, on top of the 7% GST and PST that I pay already. (OK, I’m in Canada, so tax rates are higher, but just to illustrate…) Not only that, but if 80% of my “consumer spending” each month goes to tax, I’m going to end up with less stuff than I do now. This will not make the manufacturers of the goods that I buy very happy at all, and they will quickly go out of business.
Sample numbers:
Let’s say I make $3000 per month.
35% to food & housing -> $1050
50% to consumer goods -> $1500
This leaves me 15% to save or invest, which is only $450. Currently I would be paying approximately $750 per month in income tax, give or take a bit.
Now, if that $750 had to come out of the $1500 I was prepared to spend on consumer goods, that would leave me with only $750 worth of goods (let’s ignore current sales tax, for simplicity). That’s a whopping 100% tax there.
Bear in mind that 50% of one’s income is a hell of a lot to spend on consumer goods. I probably wouldn’t actually do it - most people probably spend more like 30%. But that would mean there would have to be an even higher tax rate to make up for it. Besides, there would be no guarantee that people would continue to buy things if they were taxed that heavily. People hate to pay taxes. When the only way to avoid income tax is to not work (legally, I mean), everyone’s pretty much stuck. But if you can avoid taxes by not buying stuff, you’re going to turn into a minimalist and figure that you really don’t need several hundred CDs, a faster computer, a new car, every new toy that appears for your children, a new stereo, 10 similar but slightly different pairs of shoes, and so on. It would be the death of the consumer culture. Which I think would be a very good thing, incidentally, but it wouldn’t do much for government revenues.
End of rant, have a good Easter Weekend.
