A hundred and fifty years ago, adults were incensed about child labor. Low-wage kids were taking jobs away from hard-working adults.

Sure, there was some moral outrage at seven-year olds losing fingers and being abused at work, but the economic rationale was paramount. Factory owners insisted that losing child workers would be catastrophic to their industries and fought hard to keep the kids at work--they said they couldn't afford to hire adults. It wasn't until 1918 that nationwide compulsory education was in place.

Part of the rationale to sell this major transformation to industrialists was that educated kids would actually become more compliant and productive workers. Our current system of teaching kids to sit in straight rows and obey instructions isn't a coincidence--it was an investment in our economic future. The plan: trade short-term child labor wages for longer-term productivity by giving kids a head start in doing what they're told.

Large-scale education was never about teaching kids or creating scholars. It was invented to churn out adults who worked well within the system.

Of course, it worked. Several generations of productive, fully employed workers followed. But now?

Nobel-prize winning economist Michael Spence makes this really clear: there are tradable jobs (making things that could be made somewhere else, like building cars, designing chairs and answering the phone) and non-tradable jobs (like mowing the lawn or cooking burgers). Is there any question that the first kind of job is worth keeping in our economy?

Alas, Spence reports that from 1990 to 2008, the US economy added only 600,000 tradable jobs. 

If you do a job where someone tells you exactly what to do, they will find someone cheaper than you to do it. And yet our schools are churning out kids who are stuck looking for jobs where the boss tells them exactly what to do.

Do you see the disconnect here? Every year, we churn out millions of of workers who are trained to do 1925 labor. 

The bargain (take kids out of work so we can teach them to become better factory workers) has set us on a race to the bottom. Some argue we ought to become the cheaper, easier country for sourcing cheap, compliant workers who do what they're told. We will lose that race whether we win it or not. The bottom is not a good place to be, even if you're capable of getting there.

As we get ready for the 93rd year of universal public education, here’s the question every parent and taxpayer needs to wrestle with: Are we going to applaud, push or even permit our schools (including most of the private ones) to continue the safe but ultimately doomed strategy of churning out predictable, testable and mediocre factory-workers?

As long as we embrace (or even accept) standardized testing, fear of science, little attempt at teaching leadership and most of all, the bureaucratic imperative to turn education into a factory itself, we’re in big trouble.

The post-industrial revolution is here. Do you care enough to teach your kids to take advantage of it?
