But they aren't. This system did not work as promised. We engaged in free trade with the world and the world took advantage of our generosity. And certain Americans took advantage of the regulatory and labor arbitrage to an incredible degree:
This is only possible because of the many ways globalization allowed what we now call "the elite" the leverage cheap labor, disparate taxation regimes, subsidized industry, and currency manipulation to maximize profits and then keep them sheltered in foreign lands.
Income inequality is irrelevant, but there's no scenario where the distribution of *wealth* should ever look like the chart above. It is the direct result of Fed Reserve money printing, which is only possible because of our status as the reserve currency. Why does that matter? Because without the reserve dollar, trade deficits are almost impossible.
It's so wildly simplistic to say "They are entirely unrelated." Trade is good. For sure, no doubt. But "free trade" is a myth that cost Americans dearly. *If* Trump can stay focused, which I doubt, and if the Republicans can let go of their Atlas Shrugged fantasy long enough to strong arm the rest of the world into "fair trade," which I also doubt, we could have an economic renaissance. Personally, I think Americans like cheap TVs and debt too much to fix it, but I'm hoping to be proven wrong.
