The poor just don't know how much they are paying. That way, they get to think that what they are getting from the government is "free." It is politically very useful to the fat cat limousine liberals that run the Slave Party, while still keeping the poor on the plantation.
In fact, the poor may pay a higher fraction of their income in taxes than do extremely wealthy people who hide their income in corporate expenses, tax exempt foundations, and offshore.
The Stupid Party has TOTALLY failed to communicate these facts to the public, playing the chump while feeding the Slave Party game of class warfare. It is a huge political opportunity to do such an analysis and they are so stuck in this fantasy Hegelian dialectic they can't even recognize it.
The point is that anyone that doesn’t pay a specific category of tax will be in favor of raising the rate of that category to keep the rate lower in the category that he DOES pay.
You have to admit that the Republicans have playing the chump down to perfection.
Hidden taxes and payrol deductions are the most insidious things as they can hide the taxing on the poor and then they throw them the welfare bone and they have a voting block (the democrats do) that will never go away.
