John B. Judis makes the case that raising taxes on the rich "will not only boost the recovery, but will also discourage the wealthy from rerouting their savings into the kind of speculative activity that helped create the Great Recession":
Regressive policies can also lead to financial crises. When firms suffer from global overcapacity or merely from domestic overproduction – when a glut arises of automobiles, ships, textiles semiconductors or fiber optic cable — as happened in the late 1920s and again in the earlier part of the last decade, the wealthy, joined by corporate treasurers and bankers, have tended to pour their money into speculation rather than productive investment. The financial sector has become a casino for the rich, where they have gambled away funds that could have fueled the economy. So redistributing income through tax policy isn’t just fair; it is one way to began restructuring the economy to prevent future slowdowns and crashes.
