That's only true if the global order continues. The only reason why you can set up shop across the street from a US factory and import some goods from halfway across the world and sell it for cheaper is because the United States Navy made the risk of shipping those goods negligible. That wasn't the norm for most written history and is a function of the post WW2 order. If the US elects a pacifist president who cuts the DoD budget in half, or even if the current POTUS continues on his isolationist path then this will no longer be the case.
