I think that was the spirit of Cockburn's passage. For example, "dictatorship of the proletariat" is probably never going to make it very big over here. I think the larger argument is that there is a great deal of anti-corporate resentment that the left fails to capitalize on, and which populism could be an opening for discussing. Much of the anti-corp sentiment is starting from the wrong place (or in combination with bad ideas like racism, conspiracy theories, and idealized notions of "small producers"), but the fact is that's where a good chunk of the masses are at, so we should see that as an opening and work with it -- and hopefully transcend it.
By the way, doesn't Cuba have some of these dreaded "small producers"?
