A letter to the editor today by the chairman of the Wichita Metro Chamber of Commerce argues that a tax increase would slow the state's economic recovery. But a new report by the Center on Budget and Policy Priorities didn't find data to support that argument. "Tax measures that states used to help balance budgets during the 2002-04 period appear to have had no adverse effect on states' economies," it said. "When compared on major measures of economic progress, states that raised taxes performed at roughly the same level as states that did not." The report concluded: "In short, neither economic theory, nor recent history, support allowing a fear of weakened economic growth to affect the decision of whether or not to raise taxes."
