tariffs are a cheap temporary way to paper over an uncompetitive economy.
in the end, the US cannot and should not compete on low-margin widgets from low-wage, low education countries. We'll just get poorer and poorer if we do that, while giving companies less incentive to innovate and come up with strong new products.
I will agree that there has been one time when tariffs would have been useful: when China really started moving into western markets, we really didn't understand what a huge impact it would have. The china shock, it's called. We should have taken steps to protect the parts of the American economy that got decimated by china. Just slowed down the damage a bit to give capital a shot.
But that time is over - companies are fleeing china and it isn't so cheap there anymore.
Now we need to make sure US companies allocate capital well...not try to make low-margin widgets. No future in that anymore. The damage is done - won't get much worse.
And of course punishing Canada and Mexico with tariffs for...the drug trade and immigration...well that's just trumpian stupidity.
"The China shock (or China trade shock) is the impact of rising Chinese exports on manufacturing employment in the United States and Europe after China's accession to the World Trade Organization in 2001.[1][2] Studies have estimated that the China trade shock reduced U.S. manufacturing employment by 550,000 (explaining about 16% of the total decline in manufacturing employment in the U.S. between 2000 and 2007),[3] 1.8-2.0 million,[4] and 2.0-2.4 million.[5] Losses in manufacturing employment have also been observed in Norway,[6] Spain,[7] and Germany.[8] Studies have shown that there was "higher unemployment, lower labor force participation, and reduced wages in local labor markets" in U.S. regions that have industries that competed with Chinese industries.[9]"
