Decent comments, Anon. It's somewhat of a false argument, though, as not "everything" made in China. Dollar payments for oil is well worth noting, as have many others. With the US now a net exporter of energy, that should help shore up the dollar. What really sucks for American manufacturers is the need to turn over their patents of items produced there, as had also been the case with Japan. The loss of intellectual property rights is reason enough to question the apparent overall cost savings. The loss of American jobs, loss of income and the inability to buy more expensive American goods become a circular tailspin. Glad to see Our President addressing these issues, and although tariffs are a means of last resort, currency devaluations by the Chinese has become a common 'trick' that the WTO would need to resolve.
Despite all this, though, China has a population of around 1.5 billion people, and these people also need to earn a living. Wage exploitation is the sort of thing Marx exposes, and something the Communist Chinese must certainly be all too familiar with, but now that there are more billionaires in China than in the US, sooner than later what goes around comes around.
A lot of your other points not addressed, but not ignored either, we'll see how things are handled going forward.
