In the capitalist west in the 20th century, it seems to me we've experienced what Marx envisioned, the struggle (sometimes violent) between the upper and lower classes, again and again. It is possible to be right in your assessment and wrong in your prescription.
Strangely enough, I think we're more socialist than we think we are. A huge part of the massive US Govt is pure income redistribution, and even so we're still farther to the right than any European country that comes to mind.
