As long as the Fed keeps lowering rates, the bubble will continue growing. As soon as it looks like the Fed will have to raise rates again, get out.

Which society? There are many societies on the Earth today, and I predict that some of them will experience relative peace, security and prosperity, while others will experience conflict and instability.

It really depends on how you define “successful.” If your measure of success is based on how closely these societies resemble Western, liberal, capitalist societies, then, yeah, you’re probably not going to see a whole lot of “success,” but that’s not what these revolutionary movements were trying to achieve. I would say that first and foremost what essentially every communist movement was striving for was just autonomy and independence, and many have been successful in that regard. Vietnam is an independent nation, instead of a French colony. China, similarly, is no longer under the thumb of the British. You may not like what these nations do with their autonomy, but that is what they were striving for and they have achieved it.
