We spent several billions of dollars rebuilding a supply chain in automotive, energy, and semiconductor inputs (not just chips but the associated materials, processing, and gases used in fabrication) via the IRA, IILA, and CHIPS Act.

We need to incentivize American manufacturers to utilize that supply chain instead of co-mingling foreign inputs in an attempt to maximize margins while having taken advantage of the tax and cash incentives used when availing the aforementioned benefits during the Biden admin.

Tariffs are the easiest way to allow the American ecosystem to actually redevelop and stick, instead if wisping away due to malicious compliance. The Biden admin even considered adding similar barriers, but decided against it because they didn't want to risk a protracted trade war during a competitive election cycle.

Furthermore, most consumer goods and a number of industrial goods that would hurt the "average American's" pocketbook have alternative supply chains like Philippines, Brazil, Turkiye, India, Mexico etc that have now been made cost competitive compared to Chinese inputs.

You are suggesting that we should artificially raise prices of things to allow local industries to build and grow?

You are entitled to your opinion and I will disagree with it. This strategy will not work. People do not want to pay higher prices and will build system that work around the artificial barriers. People will even pay the 30% of so tariffs that are currently in place on China than to build the same products here. It is cheaper that way.

Also, it takes many years to build the infrastructure to build the stuff you are trying to in-source. Tariff policy changes by the month if not sooner. Investors are not lining up to build factories in the US.
