I thought I'd curtail my Dickens marathon (Nicholas Nickleby, Tale of Two Cities, Oliver Twist, Great Expectations, Our Mutual Friend) with "Little Dorrit," but decided I had to go for one more, "Hard Times." If ever there was a novelist for the "Occupy" movement, it is Dickens, who voiced many of the same concerns more than 150 years ago. People have sentimentalized his work, but a clear-eyed reading of his novels shows how deeply committed he was to economic justice.
