Those other countries charge us tarrifs much higher than 10%. China steals all our intellectual property. The do not fallow patent law at all and have been caught spying on companies and our government many time. If a company is stupid enough to have a product manufactured in China, they will copy it and be selling it before the company has their first prototype in hand. I have seen that first hand! It was not competive to have a lot of products made in the US. For that exact reason I never had some products made I was considering.
We need the be self-sufficient as a nation again. Covid proved that when all our PPE was coming from China and the stopped shipping it initially. If heven forbid a real war were to break out we would not stand a chance, because almost everything we depend on(medical supplies, steel, ships, most electronics and much more) comes from China! The tariffs may cause some short term pain, but will be well worth it in the long run.
