Apparently Canada and Democrats have resurrected some old Reagan clips with him speaking about tariffs.  Reagan opposed tariffs in general in favor of what he called free markets. He imposed them at time, like the Japanese dumping products in US markets at below cost to grab market share.  Back then conservatives opposed tariffs s protectionist, which was a dirty word in conservative circles.
Back then US manufacturing was still strong.  There were still major electronics manufacturers left in the US.  Today, almost no electronics are manufactured in the US. Almost all electronics and components are made in China or Taiwan and exported to the US.  Back then we were years ahead of the world in advanced technology and software engineering.  Not so today.
The question is, should we have imposed high tariffs on imported electronics back then as a mean of protecting our technological superiority as well as jobs? We gave away a national security advantage for quick profits.  I wonder if that was a mistake we will regret one day.
