That isn't 100% true, maybe 99% though. Anyone paying attention to politics for the last 40 years would have seen that there has always been an undercurrent of people unhappy with imports. This is the most power those people have had, but they have always been there and got significant political attention. There have thus been signs to be aware of, and those signs are things a smart company will take into consideration - they may or may not act, but they should know and consider them.

But that's the current dollar-based system. Like the gold-based system before it, today countries as a whole have to have long-term balanced trade, as measured in dollars. That's what a great many countries demanded to keep the system fair. If need be, some temporary imbalances can be forgiven by the world bank, but not much.

Outlawing or taxing imports (=tarriffs) of course helps with this.

However, if you look at economic history this always slowly lead to problems that only got resolved by fresh loans (that's what the move to dollar effectively did), hyperinflation or wars.
