It really isn't.

The U.S. can't "reward" local manufacturing (through subsidies, etc.) enough to offset the absolutely massive subsidies that China gives out like candy. (See, e.g., what China has done in the solar panel and steel spaces. Conservative estimates place the value of Chinese subsidies in those two markets alone at nearly $1 trillion dollars over the past decade.)

The point of tariffs is to eliminate the financial benefit of using lower-cost foreign providers for sourcing products for local sale.

The problem with the Trump tariffs are not that they exist, but that they are being thrown about without any thought into who or what should be subject to tariffs.

The U.S. has the biggest economy in the world. If they prioritized local manufacturing as much as China does couldn't they compete?
