"OK, what else?
It gives a good portion of the population an incentive for the tax rate to up."
-- Oh, so you're talking about the 10 - 12% of the population that lives below the poverty line overpowering the other 90%? Well, they're voting power isn't even that high.
First off, poor Americans have a much higher birth rate than the rest of the population, making their ratio of eligible voters lower.
Secondly, The overwhelming majority of felons are below they poverty line; and as you know felons cannot vote in almost every state.
Thirdly, the percentage of registered poor voters who actually show up to the polling booth is amysmal even when compared to low nationwide voter turnout numbers.
Fourthly, most of these voters, at least the urban poor, are already represented by liberal democrats who want to raise taxes; and they're not even your average liberal democrat: They're Progressive Caucus (a socialist outfit chaired by Kucinich) members!
So you think that 3 - 5% of the population that is already taken for granted by socialist democrats will be able to sway the other 95 - 97% of the population to pay more in taxes???
That reason is out the window. So what else do you got?
That reason is out the window. So what else do you got?Sure. A good portion of the population profits when the tax rate goes up.
