[BushCo: an unelected presidency of, by, and for the very rich] When Bush crows about how much an "average" U.S. family will get back as a result of his tax plan, take a look at this L-Curve (courtesy of Metafilter), to get a perspective on the extent that the ultrarich statistically skew the "average" with respect to income. If that's not bad enough, factor in his absurd stock dividends tax break, even further distancing the rich from the rest.
The economy is a complex system, but it is essentially a human invention. It can be "managed" (or influenced) in many ways. If it is not managed intentionally, then it is managed (or manipulated) by those who hold political and economic power, typically to their own advantage. It is not enough to create a strong economy. It is just as important to ask how the benefits of the economy are distributed through the population. A truly democratic society needs to find ways to manage the economy to benefit the population as a whole. This is not being done.
