Easier said then done. Check out https://www.reddit.com/r/NotMadeInChina/ for some cases where you can get a nmic product, but if you go to a store to shop or even shop on Amazon, it’s increasingly difficult. Amazon doesn’t even show country of origin, so you usually have to go to the Q&A to see if it’s been answered. Almost certainly it will say something like, “our products are proudly designed by our team in Sweden and manufactured by our partner in China.”
We could build some blueprint legislation for states that has country of origin and stick it on a website. After that we could rally our state legislature to use our blueprint. It would be easier to go that route than federally. Look at what California does with emissions standards and cancer causing items. States have power.
