Which Type of Pie Do you Prefer?

Note the rhetoric of the House Democrats. As Republicans call for a tax cut across the board, Democrats assure us that a cut for the wealthy will merely stifle the tax cut for the lower and middle classes. This argument can be refuted by using the pie analogy. Leftists see all of the money from this country as a static pie, with the predominate portion reserved for the wealthy. Few gain, the rest lose...solution: re-distribution. Free-enterprise thinking individuals see the pie as ever-expanding, while the percentages remain the same as the static pie, an increased amount for the wealthy coincides with a larger amount for the middle and lower classes. Thereby, all people gain. Due to the never-before-seen production of wealth at the turn of the century, I have my doubts that wealth is merely stagnant.
