American student loan debt reached a trillion dollars last
year. Amazingly enough, that’s more than
we owe on credit cards. At the same
time, college attendance is as high as ever.
One reason for that is the connection between having a degree and having
a job. David Leonhardt wrote in The New York Times this morning that the
unemployment rate for those with bachelor’s degrees was under 4%, which is just
over half the rate for everyone.
Is that true? Yes,
with two disclaimers. First, recent
college grads do not have such low unemployment – two years ago the jobless
rate for graduates under 25 was 9.5%. Just
because many are now in the room doesn’t mean people can still get in.
Second, correlation is not the same as causation. That is a fancy way of saying that when two
things seem to go together, one need not be making the other happen. While that rule has been well known in the
scientific community as long as there has been academic research – one mid-century
sociologist, for example, tracked the extremely strong decades-long relationship
between International Machinists Union membership and the population of the
Indian state of Hyderabad – it still fools many otherwise smart people outside
it.
The truth is easy to understand. When it is determined that two things are
related, past the point of reasonable explanation by chance, there are three possibilities. One, the first may cause or help cause the
second. Two, the second may do the same
for the first. Three, another factor may
be responsible for both of them, making it look like the two things talked
about are connected when in fact they have no relationship at all. This third explanation is by far the most
common.
Even researchers can be misled. Years ago, studies uncovered that girls
playing high school sports had lower rates of pregnancy and illegal drug use
than did their classmates. Even some
Ph.D.’s assumed that the sports caused the low incidences of these other
problems, and money was actually spent as a result. Yet while the second possibility also had
some merit – it could well be that girls with no inclination for drugs or
unprotected sex knew they would be in relatively good condition for sports, so
chose them – the third provided the answer.
Players of high school sports, except football and boys’ basketball,
tend to be of a higher social class than their classmates. The more blue-collar students are more likely
to find part-time jobs, do other things, and drop out of high school extracurriculars
altogether. Social class also correlates
inversely with drug use and pregnancy.
Therefore, the sports and the lack of these problems had a common
origin, and there turned out to be no additional evidence that either caused
the other.
Accordingly, that college graduates tend to earn more and be
employed more often is not enough of a reason by itself to judge that their
degrees are the cause. Those who put
together 120 credits with the right distribution to qualify for a major have
other abilities and qualities as well – intelligence, perseverance, strength to
overcome various problems, and the disposition to complete long-term tasks, to
name a few. That is why a few people,
such as Bill Gates and Steve Jobs, can leave their studies and achieve
tremendous success in areas where most have degrees. Those with larger family incomes, which
usually go with the high social capital almost necessary for entry to and
success in many well-paying fields, are much more likely to attend college in
the first place. Cultural factors,
especially how much hard work is valued, connect with both school attendance
and good jobs as well.
So is it wrong to go to college? Absolutely not. There are, however, four things I advise today’s
prospective students to do if they want to avoid a loan debt problem. First, they should plan on working, if they have
the opportunity, before and during school semesters, and committing some of
that money to college expenses. Second, they
should only become full-time students if they will dedicate themselves to
getting a 4-year degree – not just an associates’, as entry standards in many
fields are rising. Those who complete
bachelor’s degrees do, indeed, have better chances of being hired than those
who do not. Third, for lower expenses they
need to consider community college for the first two years. Here in New York State, tuition and fees for local
residents at Sullivan County Community College for two full-time semesters is
less than $5,000, which compares with $8,500 at some public four-year schools and
much more at private institutions. Fourth,
they should consider massive open online courses, or MOOCs, for some credits. With those things in mind, a university education
can be a great asset, well beyond helping job prospects, without being the
financial disaster it becomes for all too many.
