It seems only the very simplified narrative actually sticks, especially when it is convenient for anti-establishment types to do so (and realistically, approximately no-one really _likes_ Wall Street). But I think it's important to consider that while probably the government didn't go as far as it could, it did for the most part help prevent the crisis from getting worse for those who were not responsible while for the most part not doing much for the people working in finance, especially those that they could nail for outright fraud.
