They wont do anything dramatic as it hurts them in the process. But they can influence our markets costing investors to live with uncertainly at their whim. They don't need to crush us but you are correct to point out that they could. The troubling part is how they are scooping up gold as a possible hedge against having to pull that rigger.
The Chinese are "scooping up gold?" I hadn't heard that.
Maybe they're listening to all of the "buy gold now" ads on American TV and radio.
Gold would have been a good investment before they started saturating the airwaves with ads. Now, I'm not so sure. I think advertising has artificially inflated the price.
Of course, that could be wrong, and I could be kicking myself for not investing, but I don't think so. The last time the price of gold went way up it was because of market manipulation. When the price hit $800 back in the '70s, a friend told me the price was going to $2,000. I didn't believe it. He lost his shirt, and I didn't.
I'm expecting history to repeat itself.
