Intel does not have to bring anything back to USA -it's cheaper to produce Chips elsewhere
cheaper to have FABS near the raw resources
just getting raw materials to US is more expensive let alone any labor or Energy costs...and there is still the pollution cost
they need to invest in fabs and the fab side , R&D and in Engineers - it really doesn't matter where - somewhere cheaper is better for bottom line considering they are competing against multiple fab competitors
TSMC and samsung can produce the chips for less means AMD will have the upper hand for coming years so will any competitor Chips like ARM
