　　Ivory Tower questions the purpose of higher education in an era when the price of college has increased more than for any other service in the U.S. economy since 1978. While many college graduates struggle to find menial employment waiting tables and cleaning toilets, new student loans over the next 10 years will total $184 billion. Even the once-heroic, tuition-free holdout Cooper Union in New York City now charges students, thanks in large part to hedge fund loans and flashy facilities costing more than $170 million.
