That’s totally something my local leaders would say. States compete for business here.

Practically speaking, my vote influences how US companies operate more than it influences how foreign companies operate. Therefore, all else being equal and since monopoly implies no other choices, I’m more invested in the companies I interact with being American rather than, say, Chinese.
