Pretty good book to learn about how taxation affects the overall economy, and which kind of taxation is really paid by whom. It is also great to learn about the mechanisms behind tax optimization. It made me think about the concepts of progressive/regressive taxes. It is very in favor of increasing taxation for the rich (i.e. having a more progressive tax), but and explains how the current tax system works (in the US), how it got here and what we can do to improve on it.
