This assumes there are competitive domestic alternatives. For the vast majority of tariffed products, there are not. For one example, the domestic PCB manufacturing industry is a joke. Even with tariffs, China is literally ten times cheaper than domestic. I recently sent an order to both, and the China fab had my boards in production inside a week. The US fab took three weeks to give us a quote, which was five times higher than China for half the quantity, in twice the time. The US is not independent. We don't have a domestic industry competing on the global market. We make very little and rely very heavily on imports. What we do make is heinously expensive and not any higher quality than the much cheaper imported goods. The current trade war also doesn't spur domestic industry growth because all the materials and equipment to build out industry.... is tariffed. Plus the tariffs change too frequently for any sane person to make any kind of long term investment. Industry will wait to scale until economic forces stabilize.
