In the last two and a half generations, the number of students who go on to attend college, as a percentage of the population, has tripled. In 1959, about 20 percent of high school students went on to college. Since relatively few people were earning degrees, having one all but guaranteed getting a good, high-paying job. As a result, parents, high schools, and colleges began encouraging more and more high school students to go to college. Today, about 60 percent of high school students go on to college. But has the big push to get kids into college done anything to improve outcomes? Is the average $250,000 investment in a four-year degree at all worth it? If not, what alternatives exist? Join Antony Davies and James Harrigan as they talk about this and more on this week's episode of Words and Numbers.
