We should not be surprised if globalism is unpopular now after modern technology made it so much easier, because it was never discussed, let alone agreed to
Lynch Mob: How Globalism Lost Its Purpose and Its Credibility Without Any Globalists Noticing
The pundits sound surprised by Brexit and Trump. None of the experts saw it coming. It's shocking. It can't be explained. Yet it was majority rule. How can majority rule be a secret in today's information age? Maybe our information is poor because our discussion is lacking.
Globalism is not becoming unpopular. It was never agreed to. It was never even discussed. If we had discussed "globalism", the belief that life is better with long distance trade across international borders, then we would have used the term "localism", the opposite belief that life is better with trade limited to the local community. You can not discuss brightness without the concept of darkness. You can not discuss globalism without the concept of localism, as a philosophy. But the word "localism" is not used to mean a philosophy but a mannerism such as playing hockey in Canada, baseball in the US or red telephone booths in Britain.
