Bricker, while on the whole I agree with your analysis, I think it needs a little tweaking.
First, let me add to the mountain of evidence about the soaring costs of higher education.
I got my BA from Columbia in 2000. It cost over $100k to fund my entire education. I was not on the five year plan, either. Three years later my MA at New York University (in a technical field) cost me over 50 large.
Let’s consider the insect metaphor further. At some time in a student’s career, an ordinary student makes the choice whether to hit the books or hit the booze. This choice represents the student’s trade-off between the marginal utility he gains from current consumption and the marginal utility he gains from future consumption times the probability of achieving a given level of consumption in the futureless the disutility of studying. This probability represents the student’s belief that his hard work and prudence will pay off in the future.
This belief is conditioned on what the student believes is the state of the world. This is based on observation and assumption (and Bayes’ Rule, if you care about that sort of thing).
Let’s try to think the decision-making problem through. As a student, my net future consumption interests me. I make a prediction of my future income (based on my education) and subtract my expected debt service. I discount this future consumption by some amount because a bird in the hand is worth two in the bush. Then I can do a little math. I can figure out just how much money I would have to make in the future to offset the hard work of studying now, based on my expectations for the future. I can then do a little math and compare the marginal utility curve with the marginal cost curve to find the point at which I am indifferent between working hard and drinking hard. Even more usefully, I can see at every point on the curve what my beliefs about the world have to be in order to support a given level of hard work. In other words, to support high levels of work, I need to both value current consumption very little and I have to believe that my hard work will pay off in a major way in the future.
Let’s step out of the problem to see what conditions my beliefs and perhaps examine the returns to my efforts. As a guy in my mid-20s, my expectations are not great. I have worked four corporate jobs, dodged layoffs, ridden on the real estate roller coaster, and have endured lengthy unemployment. I am deep in student debt, and consume very little of my income. I have no credit card debt. I do, however, have a mortgage for an apartment in Manhattan that I purchased. I have a career-track job in a major financial services company doing non-administrative back office work. If I work hard enough and please the right people, one day I might make middle management.
My current consumption picture is fairly grim. My income is solidly middle-class, but my debt service is extremely high. I live well within my means. My “investments in my future” have transformed me into a slightly better paid expendable cubicle worker. I do not enjoy the fruits of my labor because I am still paying for my trip to this promised land. I have only been able to get here because my discount rate is very low, that is, I value future consumption almost as much as current consumption. While I was in college (96-00) in the height of the dotcom boom, I naturally assumed that there would be a place for a hard-working, reasonably well-connected, high-achieving ivy league graduate with solid communications and computer skills.
If I were a freshman about to make the decision whether to achieve today, I would probably look at the rapidly rising price of education, the decline in real wages, and the tense position of the United States in world financial markets. I would think hard about how likely it would be for me to make enough money to not only support myself but to compensate for giving up four years of freedom and virility by studying really hard.
I would then proceed to drink myself into oblivion and fuck anything that moves.
I have a hard time faulting 18-year olds who immediately understand and accept this without having to read The Economist and the Wall Street Journal or care about diminishing marginal utility.
Perhaps this will help you broaden your view.
