Have you read that piece? Because I have read it before, and Domhoff writes with regards to
Marxists rather than
Marx. If you're going to slag Marx for what Leninists and their derivatives have decided to read into it--well, that's a pretty curious thing to do. Not uncommon, because frankly most people haven't actually read Marx and are unqualified to opine, but I know for a fact that Domhoff
has, which makes this...well, like I said--curious.
The one criticism of that article I do have as far as what people he perceives as "Marxists" think (and I'm not one, though I do think that the general shape of what Marx describes, as opposed to either Marx's end-state conclusions or Marxists-the-fear-object group might believe) is that social democracy, which I will helpfully point out is not "Marxism", has also fairly obviously demonstrated its bones over the last decade-plus, after the article's writing, as that late-capitalistic model has created additional, shitty stresses on populations. Free market uber alles has catastrophically failed in every nontrivial employment, and while heavily-planned or fully-planned economies have obvious problems, social democracies the world over have this tendency to mostly work. I won't call them a global maximum, because that's impossible, but they have a decent claim to a local one.
Anyway, let's be real: this isn't a "basic primer" and it doesn't contain the argument you thought it did after you googled "Marxism critique". You don't have to like the way things are going, but if you're gonna pretend to an opinion, maybe give it an honest go before you offer it?
