The cost of college has parents more nervous than ever about the return on investment of the degree their kids earn. The good news is that any degree provides a return on investment. MIT economist David Autor's research results show that not having a college degree costs a person $500,000 in earnings. He calls the decision not to attend college irrational and takes journalists to task for harping on the cost of education which discourages some parents from sending their children to college. The latest figures from the Economic Policy Institute show that the economic return is there no matter where your kids go to college.
