 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. In the hunter-gatherer and in the agrarian economy, you didn't have job choice. You just had going from eight to 10 to 12 to 14 years old and getting better at doing what mom and dad, grandma and grandpa, and everybody else in your community had always done, and you would do that kind of work.
