Yeah, it's a tough one for sure. It's true that the American people have been swindled and our security compromised by terrible trade policy, but the time to have been tough about it was back in the '80s when it started. Over the last three and a half decades manufacturers have built out global networks and of course mostly taken advantage of dirt cheap Chinese labor. The net result is the American worker got screwed, but the American capitalist got rich.
The problem is, how do you undo this? Simply throwing a wrench in the cogs is likely not a smart move and will have lots of consequences. Trade wars will undoubtedly cause higher costs, lost profit, lost jobs and delays. If it goes on long enough, probably bankruptcy and companies leaving. It's hard to just change the rules to the game this far into the game.
In many ways, this is an ugly time we are living in right now and a long time coming. Many have seen this building for decades.
