This vote and the calls for protectionism in the USA and UK strike me as odd. Back in my day... it was the Conservatives and Republicans and similar parties defending trickle-down, supply-side, trade leads to growth, which leads to prosperity for everyone.
Now there's support for reducing freedom of movement in the UK (and other places in Europe), and for the USA to erect trade barriers. All this time, the official explanation was that international trade was not a zero-sum game, that if there's more trade, everyone eventually gains and that protectionism was BAD. I can't remember if state investment on infrastructure was even worse than protectionism, but in any case it was something that Chicago school/Republican politicians just would not have.
Sounds like now In Republican America, state interventions Trump China?
