Though the market adjusted, it does not always adjust in an optimal manner. With the increase in automation we've seen a shift into service jobs. These jobs are low income, low skill and often do not provide a living wage. They also don't actually increase wealth or create any real, long lasting value. This creates an income gap, which is what we're dealing with now.

The primary means of generating wealth has shifted to controlling capital from adding value, and that's not a good thing either. Those horses died off, we can't count on people to do the same.
