Advocates who are not regular adherents to the central ideas behind trickle-down economics have been handed a gift of sorts in the Republican repudiation of Kansas Governor Sam Brownback’s six-year-long conservative tax experiment. The skeleton of the experiment was simple: Cutting taxes would stimulate the economy and Kansas would see better times. In Brownback’s speeches, he said there would be no interruption of essential services. But, after years of proof to the contrary, even the Republicans were tired of robbing Peter to pay Paul each year to balance the budget. In the face of ever more bleak job and business numbers, last week they rejected the prospect of continuing on that course. The lawmakers essentially voted to reinstate taxation at close to its former levels.
