<i>Trump wants TSMC Arizona to become a foundation stone for his American golden age. But the company's story to date is perhaps the ultimate expression of the success of modern globalisation.</i><p>In other words, isolation is for idiots.<p>It is tantamount to economically shooting yourself in the foot. It doesn't lead to "greatness" but rather to decline --- a less prosperous, less competitive, less relevant society.<p>It is simply not a tenable approach to the world and TSMC Arizona is the proof. Just look at history. Every empire of consequence has been characterized by increased and expanded trade, not isolation.<p>No society has ever isolated itself into "greatness" --- and America won't be the first.
