To churn out more workers with marketable skills, an increasing number of states are offering residents free tuition to community colleges and technical schools.The move also is a reaction to fast-rising tuition costs — increases that stem, in part, from states reducing their financial support of public colleges and universities. “Everybody’s got cheap dirt — but do you have skilled workers?” Winograd said. “That’s the question states face as they recruit new industry.”But the free tuition push hasn’t produced an economic bonanza for any of the pioneering cities—at least not yet — and some states have struggled to come up with the money to keep their end of the bargain.The free tuition trend began in 2005 in Kalamazoo, Michigan, which launched a privately funded effort to combat its economic decline. The movement has quickly spread: Today roughly 200 localities offer young residents free tuition to local community colleges and technical schools.
