I wonder if this stays within the sociological tradition of functionalism, i.e. a sophisticated functionalism. Social functionalism is built on a metaphor to physiological structural functionalism. Organisms all have to have the ability to heal themselves from disease since into to every life a little rain must fall. Our bodies have immune systems and the ability to recover from sickness. Similarly with social "organisms": they have defense mechanisms. But no organism, physical or social, is immortal.
The slave mode of production existed for thousands of years. Feudalism lasted for a thousand. Capitalism has existed 500 or so, and the beginnings of its replacement have already started to appear in the last century. Declarations (not by Eric) of the permanent end of capitalism's actual replacement seriously lack historical sense of proportion. Capitalism is very young as modes of production go. It is an unreasonable and unwarranted to leap from the fact that capitalism has been able to force socialism into retreat for a couple of decades to the conclusion that capitalism is now the eternal and permanent human mode of production. It cannot be concluded ,even, from these retreats that socialism will not revive and make a come back within the next decade or two.
Thirty-five years ago, the historical record and trend was of a steady growth of socialist , socialist oriented and non-aligned, liberated/former colonial nations. The most popular American economics textbook declared the US a "mixed economy". For the last several decades, the capitalist ruling class has mounted successful counter-revolution and counter-reform. Again , it is historically nearsighted - lacking in sense of proportion , sort of left American presentism - to conclude from this ebb in the historical ebb and flow - that the Communist movement is somehow permanently defeated (????!!!). On the scale of history, it's just getting started.
The bourgeoisie don't even think that. Otherwise , the New York Times wouldn't dedicate so much ink to slandering the Venezuelan reforms nor would the right-wing accuse Obama of being a socialist.
