Adjusting to the 'new normal'

History tells us that 200 years ago, more than 60% of the U.S. population was involved in agriculture. Today, it is a good deal less than 10%. That's because technology enabled much higher production with far fewer workers and acres under cultivation. Over the past 50 years, we have seen a similar trend in manufacturing greater output from fewer people and machines. And now it's happening to plastics.
