Dickens was in no way a propagandist. Take Oliver Twist for example. In Oliver Twist, the hero is the rich man. Oliver born poor was good but the two men of the gutter who exploited children were the villains.
I'm not going to go into great analysis of all Dickens works but you should also look at Little Dorrit.
You know, just go reread these great books and try to see that he did not paint rich as evil or poor as good or vice versa.
