I take it that you think that nearly all of the value of schooling is signaling? I used to take that view too, but the accumulation of evidence that I’ve seen leads me to believe that isn’t the case.
For one thing I find it very hard to believe that we would waste so many resources on a nearly unproductive enterprise. There are plenty of entrepreneurs out there trying to make money by selling cheaper, in time and money, versions of education and they aren’t very successful. Mainstream schools have experimented with programmed learning, lectures on video, self-paced learning, etc. and none of the methods have caught on. Why wouldn’t they if they worked?
Of course its hard to believe that reading novels and poems contributes much to ones productivity on the job. So how do I square curriculum content with my view that education is productive? Here goes:
1. Education isn’t mainly about learning specific subject matter. Rather education is mainly about practicing the sort of self-discipline that is necessary to be productive in a modern work environment. High school allows you to practice showing up on time and doing what you are told. College allows you to practice and work out techniques that work for you that allow you to take on and complete on time complicated multi-part tasks in an environment where you have considerable freedom about how you spend your time. Some people may be more talented than others at this sort of thing (you come to mind as someone who is particularly talented at self-discipline), but this is also an acquired skill that one can develop with practice, and everyone needs to develop certain work habits that make one more productive at both types of tasks.
