It depends on whether it's more moral to keep a department of 5000 people employed (all paying income taxes) while avoiding import taxes or scrap the whole department because taxes make the department unprofitable.

A business will never choose to keep a department open at a loss so it can "do it's part" in paying taxes.

In this case the car manufacturer would just choose to not sell that make and model in the states and a whole department has no reason to exist
