Excellent piece from @douglasirwin.bsky.social
Reagan: "We should beware of the demagogues who are ready to declare a trade war against our friends — weakening our economy, our national security and the entire free world — all while cynically waving the American flag

On 2, check out Clashing over Commerce by @douglasirwin.bsky.social at p 574, quoting administration adviser Bill Niskanen: The Reagan administration's strategy was "to build a five-foot trade wall in order to deter a ten-foot wall [that would have been] established by Congress."

Joel Mokyr: What Today's Economic Gloomsayers Are Missing In The Wall Street Journal, Joel Mokyr writes that science is enabling invention like never before and in ways that will improve life but isn't captured by GDP statistics.

"The responsibility of economic historians is to remind the world what things were like before 1800. Growth was imperceptibly slow, and the vast bulk of the population was so poor that a harvest failure would kill millions." - Joel Mokyr
