Andrew Roth, interim president of St. Bonaventure University (NY), writes:  Imagine Houghton without Houghton or Ithaca without Ithaca. Elmira without Elmira or Utica without Utica. Now imagine Allegany and Olean without St. Bonaventure.  For all the hand-wringing private college officials in the state are doing, and justifiably so, about Gov. Andrew Cuomo’s proposal to provide free tuition to all SUNY and CUNY colleges, the vastly underplayed story is the devastating impact the initiative could have on small cities and towns in New York.
