Blaming the poor for not knowing their place is a pretty strange take. Anyway, I enjoyed that movie, but had mixed feeling about it. Checking my notes about it, I was unsure about the didactic sequences using the stars. In a way it's nice that these explanations are there (the Wolf of Wall Street lacked those for instance), but it kinda felt like talking down to the viewers in a strange "Millionaires explain things to the paupers" way. To limit this effect maybe they could have used some meta comedy effect that emphasized they were not the author of the text being delivered (like they could mess it up or be surprised by it). I guess you can argue that the very nature of the sequences already make them meta comedy, but... yeah. Also, the main characters discover how fubared things are and their first instinct is wonder how they can profit from this knowledge. This is in part counterbalanced by some scenes (Melissa Leo pointing at the hypocrisy, Steve Carell's hesitations, Brad Pitt's vigorous reality check...).
What is certain is that the film is often very funny unlike Margin Call, but Margin Call is crazy good even though I must confess its genius did not hit me the first time I saw it. I caught it on TV a few years later and scene after scene after scene are amazingly written and cleverly directed.
