@twentyfive,
You're still conflating political ideas with economic ideas. NATO has little to do with trade. But I'll respond anyway. NATO is a military alliance. We are allied with countries that can't defend us. But we can defend them. So why should we help defend countries that can't defend us? Even if they pay us to do it, what's the point? We don't need an overseas empire. And the American military is not for sale or for rent to the highest bidder. Regardless, even if Russia literally took over every single country on earth except for America, and then they all waged war on us, we would still win. America is so wealthy and has such a powerful military that we could literally defeat a coalition of the entire world. Our nuclear stockpile alone is sufficient to destroy the whole world several times over. So what's the point of NATO?
Second, intellectual property is the product of someone's mind, and once an idea is out there in the world, you can't own it. You can't reach into someone's mind and control it. People will always make art and express ideas, with or without a copyright. Artists paint public murals, people post videos on YouTube for pennies, and you and I are expressing ideas publicly right now for free. I'm not worried about Hollywood stopping all movie production just because of a few bootleggers in China.
As for currency manipulation causing world trade to stop, I had a good belly laugh over that one. We've been manipulating our own currency for decades. What did you think quantitative easing was? I'm totally against it, but if China wants to drive its own currency to zero in pursuit of a mercantilist fantasy, why should I complain? It just makes their products cheaper for me.
But as for the topic of trade in general, I should clarify: when I said "service economy," I meant all jobs that aren't manufacturing export-related jobs. Butchers, bakers, carpenters, electricians, actors, writers, retail clerks, managers, doctors, engineers, architects, customer service reps, teachers, construction workers, realtors, pilots, mechanics, researchers, etc., all these jobs do not involve working on an assembly line, manufacturing products. All of these jobs would still be here even if America stopped manufacturing anything at all. Which of course is a ridiculous hypothetical: we manufacture more than any country on earth except for China. We make turbines, fuselages, cranes, trucks, tanks, satellites, medications, etc. It's not the kind of stuff that you see stocking the shelves at Wal-Mart, but we still make tons of things.
Anyway, you should try what I suggested: go to a local university and ask an economist what he or she thinks of unilateral free trade. In other words, ask what he thinks about America completely tearing down trade barriers even if other countries don't follow suit. You can even print out a copy of this conversation and show it to him. (Maybe cross out our screennames so that he won't know which website this came from LOL.) I don't have an abundance of formal education, so perhaps they could explain these concepts to you better than I can. Let me know what they say. Your ideas and Trump's ideas on trade are very old fashioned, and they were quite common in the 17th century. But at some point, the ideas of mercantilism were replaced by economic liberalism, and the ideas of Adam Smith, John Locke, and the enlightenment came to dominate economics. One of those ideas was free trade. Sadly, the ideas of Karl Marx and, later on, John Maynard Keynes also emerged, but free trade remains a standard theme of modern economics and hasn't been challenged.
