I don't know that we can call Marx right; we can, however, definitively declare Francis Fukuyama wrong. History, even considered as merely a dialectic between opposing models of resource allocation, is far from over.
In terms of the fact that capitalism goes in "rise and fall" cycles, yes, this much seems clear. In terms of the idea that the public ownership of wealth is inevitable, hardly.
As Thatcher wisely said, "There is no such thing as society."
So capitalism I think continues. Just a few folks will blow their brains out along the way. Survival of the fittest, what can I say. Don't blame Darwin or the capitalists. It is just the laws of nature. As Elton John sings, "Who makes the call and who gets to choose/who gets to win and who gets to lose/it's like rolling dice in the belly of the blues/and the blues never fade away."
