All companies pay taxes to the US government. They can make special deals and tax breaks if ask them to move out of China. But you knew that because you're from the USA right? Everyone pays taxes, private or not. Every company wants the best deal. The USA can do that if things escalate further. The American people can boycott that products made in China if it got worse.
LOL yeah right. The US can't afford it. All major companies are enjoying the cheap workforce Chia is offering and that is 5 cent per hour where in the US cost at least $10 per hour. All companies will simply give the US the middle finger and do business somewhere else as the world doesn't revolve around the US after all. The laptop you are using to participate in this forum is made in China, your phone, the cloths you wear, the chopstick you use to eat with....etc. Heck even the US debt is mostly owned by China. Get off your horse mate and face the reality. If China were to impose sanctions, the US market would crumble.
