I had a far left instructor for World History 101. On the reading list she assigned a book on population that actually had raw data in it. The stats focused on Western Europe and the U.S. because they had the oldest data. When I looked at the data I saw right away that birth rates begin to fall when a country goes through industrial development. And they keep falling to the present. Of course, the author didn't care and still made the alarmist arguments. Just like Al Gore putting the ice core data that refutes AGW into his movie.
I could see way back in the 70's that there was no population bomb to explode and that Europe's birth rate was plunging toward replacement levels and possibly below.
I had that moment in the fall of 1980 when the Poli Sci prof was talking about “workers controlling the means of production.” It was instantly obvious he’d never spent a day in the real world. Having worked commercial construction all summer, I knew turning the means of production to the guys at Rome Builders was a bad idea.
It was apparent to me that guys like Prof. Hansen saw a political means to seize control over economic assets they had no idea how to create or operate. It was theft, and as usual, the thief was going to trash the goods he stole.
