“It” wasn’t a “trade war” when back in 1979 TPTB started or decided to give China and other backward undeveloped countries all the domestic American consumer product jobs, and “its” not a trade war now.
Those trends simply went too far and had to stop and reverse on their own. And re the global economy failing? It’s NOT capitalism failing. Its international socialism that’s failing because they ran out of other America’s money to spend.
