Don’t disagree with your assessment. But tariffs can help encourage overseas firms it is more profitable to locate industrial activity in the U.S., as some in China are already doing.
How so?
The only thing that motivates free enterprise is profits (price minus cost). Government's high taxes, unconstitutional suffocating regulations, unconstitutional forced business-killing minimum wage, unconstitutional competitive-killing subsidies (bribes), and unconstitutional union protection has forced such higher costs creating such an unfriendly business environment in the U.S. that industry has fled to other countries with much friendlier business environments.
Industry doesn't care if a country shoots itself in the foot with tariffs. They'll keep chugging along doing what they do best and if they have competitive quality with competitive prices, they will be successful regardless of another country's misguided tariffs.
The key to economic prosperity is REMOVING GOVERNMENT BARRIERS & INTERFERENCE. Doing away with the things listed above actually fixes the problem motivating industries to return and prosper in an opportunistic and competitive business environment. Those measures Trump has begun implementing to remove those government barriers is why businesses want to return and is why the economy will take off, grow, and prosper mightily.
