Not to dive into politics here, but we had post war manufacturing for a long time. Trade deals and this "open markets" orthodoxy that wasn't shared by foreign countries charging us tariffs on American made exports is what killed manufacturing. If companies found that they had free access to American consumers no matter where they were located then they soon afixed their eyes on labor costs as the major cost driver. Immediately it became clear that they could make more money by manufacturing the product with cheap labor elsewhere and absorb the increased shipping costs (which was dwarfed by labor expenses anyway). Tariffs change that calculus and directly address the fact that outsourcing was actually very sustainable for foreign manufactured goods (just not for American employees). Americans have money and have been imprinted with a desire to consume. We're the perfect market for anyone making widgets on a grand scale. Why shouldn't they pay a fee to get into this market, just like the fee they charged us to get into their market. Seems like common sense to me.His intentions are simple - make America great again. How do we do that? What's the biggest difference between the post war boom and now? "Made in America" So we'll bring production back to the US. But what his plan doesn't address is the reason production moved overseas to begin with - a softening post war economy and CEO's who did what they could to continue their own lifestyles, at the expense of the employees. And then the cycle continued for 5 decades because no one wants to face the hard truth that outsourcing isn't sustainable. The irony is of course Trump is one of the fat cats who lines his own pockets. But this is a PR move to appeal to the sensibilities of the people who elected him and it's a way to wave his dick around.
He doesn't have an end goal, other than to make money and satisfy his own ego. That's all this is anymore - a power trip, not a strategy game.
