I think you messed up your grammar which makes the sentence hard to read but I think what you're getting at is right. College is a service, which is why you pay for it. If it didn't provide value, nobody would use it. Free college is a danger because there's no good way to assess its market value or whether we need it at all. It's only by adding value that we create wealth, and some of these NSF grants are just jobs programs for engineers.
