Say you're in the midst of the worst economic meltdown in decades and face a $360 million shortfall next year. As an elected leader of Miami Dade County, you send a clear message to voters by:A. vowing to take public transportation to work.B. joining a car pool.C. getting a BMW 500i Gran Turismo.The final answer is exactly what Mayor Carlos Alvarez did when he picked out a new set of wheels using $500 a month in taxpayer money. With a car like that, he'll have to fork out some of his own cash to make ends meet. But that got his minions thinking. On March 4, Miami-Dade commissioners agreed by an eight to four vote to ask voters to increase their pay by around 50 percent, from about $60,000 to $92,500. A little later, reality kicked in and they pulled the measure. Chutzpah? These guys are meshuga!
