That is what is called regressive taxes and its nasty and cruel. The rich get to buy more thousand dollar wine bottles while the poor go without food.

During his presidential campaign announcement speech last week, Texas Gov. Rick Perry lamented the "injustice" that nearly half of all Americans -- the poorest half -- "don't even pay any income tax." But in Texas, the tax burden is disproportionately shouldered by those families living below the poverty line, newly-released data from the Census Bureau show.
While Texas is generally considered a low-tax state since it doesn't impose a personal income tax, a new analysis by the Institute on Taxation and Economic Policy finds the state's tax laws are actually "redistribute income away from ordinary families and towards the richest Texans."
