There’s swirling argument going on over at OTB (again) over the value of higher education. My own reactions are extensive enough I thought I’d put them here.
Let’s first clear the air a bit by defining the parameters of the discussion. The post at OTB is entitled Is College a Scam? I think that to come at that question reasonably we’ll need to constrain what we’ve discussing a bit. Let’s divide the population into four groups. The first group is people who intend to pursue careers in the professions, especially professions that require post-graduate education (e.g. physicians, dentists, lawyers, architects, etc.). To be able to succeed in that ambition they’ll need intelligence slightly above the median and will need to receive an undergraduate degree with pretty high marks, especially for the more competitive fields.
For this group college education is necessary to their plans. For some of the fields, e.g. physicians, dentists, higher education has, historically, definitely not been a scam. Their return on investment is excellent. For lawyers the situation is more complex. Returns (as measured by incomes) for lawyers occur in a bimodal distribution. Most of those in the upper portion of that distribution are graduates of the top law schools, editors of legal review, etc. While their return on investment for higher education is excellent, the return on investment for those in the lower portion of the distribution whose median income is $35,000 a year, to the extent that higher education is a means towards the end of the income of those in that higher portion of the distribution, higher education has been at best a poor investment and at worst a scam.
The second group is composed of individuals with intelligences significantly above the median who don’t plan on pursuing the professions. These are the Bill Gateses, Mark Zuckerbergs, and so on. For them higher education is a waste of time. They can achieve their objectives in other ways. They shouldn’t be held out as examples to emulate: they’re exceptions, not the rule.
The third group is composed of those with intelligences that are significantly below the median. If they gain admission to college at all, they will find college such a grueling and unrewarding experience that, at least IMO, they are unlikely to graduate. It would certainly require enormous determination. I believe that for most of those in this group higher education is a scam.
The fourth group is composed of those with median intelligences plus or minus a standard deviation. That’s about half the population and I think that’s really the group that we’re discussing. This group is capable of graduating and achieving some degree of mastery of the information that is taught. Without great determination, they are unlikely either to be admitted to post-graduate education or, if admitted, master the information.
Rather than answer the question of the worthwhileness of higher education for this group directly I think I’d express my thoughts about the worthwhileness of higher education this way. For one thing I’d really like to see some more refined data on return on investment. Something that controls for age, parental income, fields in which incomes are normally distributed, and any number of other factors.
However, rather than argue about whether higher education is a good investment for most people, why not focus our attentions on making it a better investment? Through the application of technology we should be able to re-invent higher education so that it is significantly less expensive, maybe free, more rigorous, and more effective. That’s an objective that I think a state or a cooperative of states should be able to accomplish.
Update
It occurs to me that there’s a fine distinction I was trying to make that may have been lost. I don’t anybody should be prohibited from seeking higher education, however, I don’t think that everybody should be encouraged to seek it, either. I don’t think that higher education should be a prerequisite for a decent life. I think that we don’t do nearly enough to ensure that every person finds his or her highest and best use and that higher education is not completely relevant to that.
