Ever since I was young adults have been complaining about paying taxes. Luckily at a young age I understood how important it is to have a tax system to pay for schools, roads, parks, social security, emergency aid, and other resources that we use daily and that improve our lives. It took longer to realize how our tax system works. Thanks to the Occupy movement we are becoming more aware of how financial inequality is crumbling our nations financial security. To change the corrupt and unfair tax system we need to understand it. Transparency and education will show us how and we can move forward with informed minds.
For your convenience, here is a video made by The Urban Institute that helps explain the simplicity of who is paying what.
They also have an interesting PDF report on taxes and inequality, http://www.urban.org/publications/413067.html
Wikipedia has a summarized history of taxes in the U.S. that shows how much taxes have changed since conception. http://en.wikipedia.org/wiki/Taxation_history_of_the_United_States
