The century old strawman argument:

The Progressive argument against tax cuts hasn't changed in a century. The problem is that the trickle down theory has never been espoused by any Conservatives or conservative economists. We have always said that high tax rates kill economic growth and distort economic activity in unproductive ways. Yet over and over again we hear, at the mere suggestion of a tax cut is, "for the rich" and "all you want is trickle down." The reality is, every time there are high tax rates affluent people's income quickly shifts to low or tax free investments and the revenue collected disappears. The problem with high tax rates is that you can't tax economic activity that doesn't happened and in a downward spiral, government, in search of revenues, taxes more and more those who can't escape the taxes because they don't have the flexibility of the affluent. All high tax rates do is place an increased burden on those who really can't afford it.
