And do you know where the tools and dies to make those things come from? Where the robots that work at those lines come from? Where the chips in those robots at those lines come from?
Hint: not here. Even basic machining is cooked here. Go on Xometry and compare the pricing of any simple design made in USA vs. China and you’ll see, we can’t competitively do the basics anymore (you conflate basic with crap).
And how much of what China makes is dependent on imports? Breaking news: the global economy in 2026 is highly interconnected.
If you go back to WWII America was the China of the world: mass produced products if midrange quality.
Europe owned high end quality, especially Germany.
Most Radar technology was invented in the UK and then sent to the USA where American engineers would redesign it for mass production. You'd have a magnetron that the British machined at great expense and the Americans would redesign it so it could be stamped out by the thousands.
Germans would look at the wrecks of bombers they shot down. Early on they'd look at a B17 and say "this thing is crude" but by 1944 they'd look at a late model bomber and say "we don't even know how they made some of this stuff".
People have it entirely backwards. They think if you can do high end manufacturing the low end is easy. In fact if you can do mass production of low end parts with consistent quality then high end stuff is easy.
