There is Zero 0% chance that a Display like the XDR is Made in the USA. Heck I’d go further and say I do think there are any working plants or facilities or trained workers in the USA to manufacture a display like the Apple XDR Display.
There’s a handful of USA OLED startups Maybe a single Surgical Grade Monitor manufacture that are used during Surgery but those cost $40,000+ and are sold through hospital vendors Not to the public.
