It’s been said that about half of all people have an IQ less than 100. Some psychologists have pointed out that those with IQs less than 90 have a difficult time finding good work in advanced knowledge-driven economies, and manual labor has been either exported to other countries or replaced with robots, leaving part of the labor pool underutilized.
So the shape of the idea that would generate 9%+ GDP growth is a set of technologies and/or political configurations that bring people of all IQs enthusiastically into the labor force. Not just employment opportunity, but situations that would be gleefully embraced, and productive, regardless of IQ. Work that is useful and fulfilling and worth doing for all involved.
This is not the actual idea, of course, only a statement of what might be its shape. If I actually had that idea, I would be talking to venture capitalists at this moment rather than typing this comment.
This would be good only for a temporary gain of three to six years of high growth. After that, we would be at full employment, and although the indirect gains would likely flow for a long time, national growth would likely fall below the 9% figure.
What’s more important, though, is that such an outcome (bringing gleeful and productive employment to many) would make a lot of people happier, regardless of GDP growth.
Took me zero time to adopt what jsaltiver says here. I’m fortunate to have had a lot of experience programming, and then recently done a lot of custom furniture and woodworking. There is a very large difference between just thinking about something and working with its physical manifestation (or source code). Often, with wood and buildings, theory is worth a tiny fraction of tacit knowledge.
Something to mix in here: The Secret of Our Success (Henrich) is partly about learning from others, and how that dominates over self-discovered knowledge. It’s worth it to reflect on whether/how he and the other cultural evolutionists are right about this when so much actual knowledge must be accumulated via tacit means. “Learning from others” might be just as bad as thought knowledge unless it is done the right way.
