Trickle-up economics

Larry Beinart has a good analysis at the HuffPost of how wrong Republican economics are for the U.S. (Bushenomics 102: Reality.
One point I’d like to reinforce is this: If you want to cut taxes, cut it from the bottom up. The money will get spent, stimulating the economy. and the base of the tax cut will be broader. The wealthy will get benefits from this too.
If there isn’t enough revenue available to cut taxes across the board at the bottom (one way to do this is to raise the standard deduction), then maybe the money isn’t there for tax cuts at all.
