It was mostly about derivatives. They did not mention taxes at all.
I don't recall any solutions, other than the implication that something is rotten about what has been happening, and the implication that Wall Street and Politicians should stop doing the rotten things they are doing. The first step is making people aware. I'd say less than 5% of the people in the country even have a clue.
It was a decent intro to the topic. They interviewed a number of people who actually worked on Wall Street.
I am reading Predator Nation by C H Ferguson, which I recommend. It covers a lot more material, although still the details of the derivatives are glossed over more than I'd like, as they are in pretty much all public information.
