.... eh, Clinton open up trade with China, yes. But China is not a superpower, they're too export dependent, and don't have enough domestic demand to keep they're economy afloat. And China has not devastated our economy. We run a trade deficit with them, and they own over a trillion in T-bills. But their currency is tied to ours, they need us to keep they're economy going. They can't sink our economy without destroying they're own. They also invest TONS of money into US capital. If anything we're in a mutually beneficial relationship. I mean... GDP went up after we opened trade with them.
I'd also argue that US economic decline is more correlated to a lack of reinvestment in manufacturing and agricultural industries. We also let Wall St run amok and torpedo themselves.... I'm not the biggest fan of Clinton's policies, and yes, his polices have had unintended consequences, but I don't think China is one of them. I think fear of China is slightly irrational
