Rigged Economy or Statistical Inevitability? Wow, nice post. I am glad events turned out this way, as my post was essentially a rant.
Here's what I think about what you have in mind. The tendency for the rate of profit will actually accelerate... upwards.
Marx was a guy living in a time when productivity increases such as seen today were nil, zero, uncomparable.
You will most likely see the automatic stabilizers in the economy... failing to account for the deflationary spiral we will most likely experience (think Japan). After Japan will be South Korea, the Scandinavian countries, Germany France, and lastly the US. The US will be last because the greenback is still the unit of exchange across the world and their demographics are growth-oriented.
Fueling hamfisted growth will be from BRIC countries (except Russia, there's something economically downright fucked in that country).
The neocons are having an orgy given that they convinced the masses that trickle-down works. It does work; but, only through trade. Furthermore, since the whole world seems to have adopted the fiat system, and accepted the implicit neo-Keynesian sentiment that goes along with it, I see the Austrian school making a comeback sometime soon.
Everyone should be cumming in their pants.
