Start putting tariffs on anything made with Chinese rare earths. Since China is a net exporter, they have the most to lose playing these games.
That's ridiculous. The largest purchaser of rare earth minerals are US companies. Tariffs are meant to encourage people to buy products from other countries, mainly the host country. There really are no other producers of rare earth minerals to choose from, not in quantities large enough to satisfy demand. That would be like increasing taxes on oil to encourage people to not buy from the middle east. There's just not enough being produced outside there to satisfy demand. The economy would crumble. What the US needs to do is encourage production elsewhere of these minerals, so we're not tied to China so much.
I believe what he is saying is for the ISP's to stop advertising "All you can eat buffet's" and introduce tier'd systems.
