now, but even if you’re not, you’ve probably spent a good chunk of your life getting educated.

Adriene: Nearly all countries require at least some mandatory schooling and most of those

countries provide that education for free.

Jacob: But nothing is ever actually free. There’s always an opportunity cost. The money

and resources that go into education might be used to fund other social programs or bring down the debt.

Adriene: And if you go to college, the cost is not just the tuition and books, it’s

also the income you could have earned by going straight into the workforce.

Jacob: But is college even worth it? Well, let's look at the economics of education.

Adriene: Why do governments spend billions funding universal public education? Why not

just let profit seeking businesses handle it? Many argue that if education was entirely privatized

it’s likely that some children would be excluded, and that would make society, as a whole, worse off.

Education is a positive externality. Education benefits individuals by helping them get a

job and earn more income, but it also benefits society as these individuals create art, invent

cool stuff, cure diseases, and make interesting conversation at parties. More education increases

productivity, GDP, and standards of living.

So, today we’re going to look at the education system in the United States. We’re talking

about the US not only because we make Crash Course in the US, but because education in

this country is going through a lot of changes. This way, we get to talk about things like

education standards, vouchers, and student debt.

Now, to be sure, there are places that do things differently. For example, in the European

Union college costs a lot less than it does in the US, or is even free.

In America, the government pays for primary and secondary public education and heavily

subsidizes college. In 2015, the federal and state governments will spend about 634 billion

dollars on primary and secondary education. That’s an average of about 12,500 dollars

per student each year. Which is a lot of money.

And despite all that spending, the US has some serious problems with its education system.

One of the biggest is inequality. Students from low income families tend to have lower

math and reading test scores than those from higher income families. African American,

Latino, and Native American students are much more likely to drop out of high school than

Jacob: For some economists, the best way to level the playing field is to focus on funding.

They argue that the government should pay for early education programs, and provide

extra money for disadvantaged and low-income students.

For others, the answer isn’t just about more funding, it’s about having more competition.

Some economists support charter schools and voucher programs that allow parents to pick

schools, or open enrollment among or within school districts.

Now in theory, this forces all schools to improve, or face losing their funding. Other

economists focus on the teachers, and argue that they should be incentivized to improve student performance.

Each of these ideas have been implemented in the US, with varying success. We have yet

to find the magic formula, but it’s clear that the first step to improving equality

is to invest in primary and secondary education.

Now, what about higher education? Is that a good investment? Well, keep in mind that

there are many reasons – not all of them economic - to go to college, and to be educated

in general. People go to college because they enjoy learning and want to know more. Or maybe

they want to put off getting a real job. But in economics, we focus on financial benefits. So, is college worth it?

The fact is, college graduates, on average, earn more. Economists call this the “College Wage Premium.”

Among 25-32 year-olds, college grads earn  an average of $45,000 vs $28,000 for those who only

have a high school diploma. Also, the unemployment rate for college grads is pretty much always lower.

Right now, for people over 25 with a college degree, unemployment is around 3%. Now, that's vs. around

5.4 percent for those with only a high-school diploma. And it’s 8.6 percent for those who didn’t

finish high school. So bam – college pays off, case closed.

Adriene: Well, not quite. The people who graduate from college are NOT a randomly selected group.

First, it takes a modicum of intelligence and dedication to even get into college. Second,

you have to receive a fairly good primary and secondary education to be able to keep up with college work.

Third, the students who attend college are more likely to come from well-off families

with educated parents who have the time and energy to help encourage their success.

So when you compare college grads to those with less education, you’re often comparing

people from advantaged backgrounds to people without many of those advantages. The fact

that college graduates make more money isn’t just about college. It’s also about life

circumstances. Let’s go to the Thought Bubble:

Jacob: Economists point out two main explanations for why college graduates earn more. The first

is the “Human Capital” theory. The idea is that going to college actually teaches

you skills that’ll help you get a higher income job. The second theory is called “Signalling.”

This is the idea that some students have shown they're smart and hard-working, but in a job interview,

EVERYONE is going to claim “Sure, I’m smart and hard-working!” even applicants

who aren’t. So the talented applicants need something else to validate their abilities

that can’t be faked by others. A college degree sends a clear signal. "Look at me!

I graduated Summa, and I’ve got the notarized transcripts to prove it!"

Many employers would prefer an applicant that has an actual Harvard degree over one that

has an equivalent self-taught education. But a college degree isn’t only about signaling

ability, we could accomplish that with a test that would take one day and $100, rather than

4 years and potentially hundreds of thousands of dollars. College degrees send other signals

about socio-economic status and background.

BOTH the human capital theory and the signalling theory are compatible with the data: both

predict that college graduates would earn more, which is what we see.

But economists have tried to figure out which theory is correct. They have compared the

earnings of people who have earned 7 ½ semesters worth of college credits but didn’t graduate,

to people who finished and got a degree. Both groups received about the same amount of education,

so if the Human Capital theory is correct, they should earn about the same amount of

money. If the Signalling theory is correct, those with degrees should earn noticeably

more, and they do. But it’s a smaller gap than you would find from just comparing high

school and college grads. It seems that both theories apply.

Adriene: Thanks Thought Bubble. Okay, so we know that there are significant financial

benefits to completing college. But what about the costs? Going to college can be really

expensive. Often more than most families can afford. In the US, students have over 1 trillion

dollars of debt. That’s more than Americans owe on their cars or their credit cards!

More students are attending college than ever, and more of those students are paying for

at least part of their education with loans. In 2012, almost 70 percent of students took

out loans to pay for tuition, and the median amount they borrowed was around 27,000 dollars.

By comparison, in 1993, the median amount students borrowed was around 12,500 dollars.

And that’s just the median. So even if some of the hand-wringing over the total amount

of student debt is overblown, the average student really is taking on a larger burden.

So, this is all thanks to higher tuition, right? Well, not exactly. At four-year public

universities, the average cost of tuition, room and board has gone from $10,600 dollars

in 1994 to $18,900 in 2014, when you adjust for inflation. The average tuition at comparable

private universities has risen from $26,500 to $42,400 during the same period.

But that rising tuition number is the “sticker price” for college – in fact, most students
