I think there’s reason for some skepticism about how fast things are actually moving. There’s a lot of aggregate data that don’t support the idea the labor market is changing or the economy is changing as rapidly as this very dramatic story. The premium to higher education has plateaued over the last 10 years. We see evidence highly skilled workers have less rapid career trajectories and are moving into less skill occupation if anything. Productivity is not growing very rapidly, and a lot of the employment growth we’ve seen in the past 15 years has been in relatively low education, in-person service occupations.
The second point I want to make, when we think about how technology interacts with labor market we think of substitution of labor with machinery. […] What is neglected is that it complements us as well. Many activities require a mixture of things. it requires a mixture of information process and creativity, motor power and dexterity. if those things need to be done together if you make one cheaper and more productive, you increase the value of the other.
On the one hand we have enormous anecdotal evidence and visual evidence that points to technology having huge and pervasive effects. Whether it is complementing workers and making them much more productive in a happy way, or whether it is substituting for them and leaving them unemployed can be debated. In either of those scenarios you would expect it to be producing a renaissance of higher productivity.
So, on the one hand are convinced of the far greater pervasiveness of technology in the last few years, and, on the other hand, the productivity statistics on the last dozen years are dismal. Any fully satisfactory view has to reconcile those two observations and I have not heard it satisfactorily reconciled.
If you believe technology happens with a big lag and it’s only going to happen in the future, that’s fine. But then you can’t believe it’s already caused a large amount of inequality and disruption of employment today. […] Let’s take retailing. You can imagine you can have all kinds of spiffy technology so you no longer have to have people behind cash registers. The problem is you wouldn’t expect the people behind the cash registers would get fired before the people working the systems got the new systems working. […] I understand why it might take years for it all to have an effect. What I have a harder time understanding is how there can be substantial disemployment ahead of the effect of the productivity.
That is, if you thought that it just was impossible to put in these systems and so forth, then you might think that in the short run it would be a big employment boom. You have to keep your old legacy system going and you have to have a million guys running around figuring out how to put the new computer system in.
I think the [education] policies that Aneesh is talking about are largely whistling past the graveyard. The core problem is that there aren’t enough jobs. If you help some people, you could help them get the jobs, but then someone else won’t get the jobs. Unless you’re doing things that have things that are effecting the demand for jobs, you’re helping people win a race to get a finite number of jobs. […]
Folks, wage inflation in the united states is 2%. It has not gone up in five years. There are not 3% of the economy where there’s any evidence of hyper wage inflation of a kind that would go with worker shortages. The idea that you can just have better training and then there are all these jobs, all these places where there are shortages and we just need the train people is fundamentally an evasion. […]
I am concerned that if we allow the idea to take hold, that all we need to do is there are all these jobs with skills and if we can just train people a bit, then they’ll be able to get into them and the whole problem will go away. I think that is fundamentally an evasion of a profound social challenge.
