If you wanted to tax capital via equity stakes, you'd simply have demanded a much larger stake.
What we're doing is starting down the road of "capitalism with Chinese characteristics". It's a tacit admission that the Chinese model can be effective at achieving a nation's strategic economic goals. (More effective than the model we previously championed.)
The real flip side in all of this is that everyone else sees what we're doing for what it is, and they also implement capitalism with Chinese characteristics. Which in and of itself wouldn't be bad. But what if nations like India or Indonesia turn out to be just flat out better than us at it?
Or, God forbid, the nightmare scenario, which would be nations like Brazil being better than us at it?
