Gov. Cuomo on Tuesday unveiled a plan to provide free tuition at state colleges and universities for low and middle income New Yorkers. Flanked by Vermont Sen. Bernie Sanders, Cuomo said the program — dubbed The Excelsior Scholarship — would offer free tuition at state colleges and universities to “any family” earning $125,000 a year or less. “College is a mandatory step if you really want to be a success,” Cuomo said during an appearance at LaGuardia Community College. “And the way this society said we are going to pay for high school because you need high school, this society should say we’re going to pay for college because you need college to be successful.” Cuomo said the program, which would require approval by the Legislature, would combat the rising costs of college and the rising debt loads faced by students, which in New York average about $30,000 per student.
