 history nerd for a minute. There are only four kinds of economies in human history, right? There were hunter-gatherers, there was settled agrarians from the Fertile Crescent 10,000 years ago until 150 years ago. Obviously, we still have unbelievably productive ag in this country, but at the scale of how many workers are needed, well under 2% of the populace. So you had hunter-gatherers, you had agrarianism, you had industrialism, and you had, what's this economy? The knowledge economy, the IT economy. A lot of sociologists just call it the post-industrial economy, which is another way of saying we don't really know what to call it, so let's call it the after the last thing thing.
