Funny how a lot of the people who are enamored of the Chinese model, aren't capitalists. The real attraction is for stoking authoritarian fantasies of all flavors. Want a high speed rail or massive infrastructure/social safety net projects? China made it happen. That's your authoritarian socialist viewpoint.
Want favorable or unique business advantages or just doing away with the arbitrary rules imposed by the thoughtless masses? Just think what profit you could make with the power available to the Chinese government! There's your authoritarian capitalist viewpoint. Want people to be good and the society perfect? Let's make them be good and the society perfect via the Chinese model! There's most of your utopian viewpoints.
I imagine many of these large investment firms have direct or indirect access to zero percent federal reserve loans (going on six years with no end in sight) and they would be foolish not to speculate on Alibaba with house money.
Well, the Fed has admitted that it purchases a lot more than just federal treasuries and bonds. There must be some obstacles in place though else we'd have a lot more inflation. The economy isn't acting like there's easy, unlimited credit else we'd see more and large asset bubbles than we currently see.
I think one of those obstacles is reserve, namely how much concrete assets one needs on hand to cover leveraged investments.
As to the "Business Plot", it's worth remembering that those guys alleged to have been plotters got shafted a lot by the Roosevelt administration who let us note did stuff that should have been outright illegal like stealing privately owned gold in the US and attempting to pack the US Supreme Court. It was not unreasonable at the time to expect the US democracy to be near its end. In that case, why not fight the emerging dictatorship on its own terms?
Let us note that this sort of business-backed revolt worked in both Iran and Chile and similarly failed in Cuba and recently, Venezuela. I can't think of an example, win or lose that didn't turn out badly for the country in question. Maybe we should instead work on not letting things get to the point where businesses are desperate enough to back a rebellion or coup?
