Here I was sitting in a debate with this hardcore freeper who was spouting off the wonders of a flat tax (isn't that a regressive tax, by definition?), the dangers of minimum wage and market regulation and all I could think of was 'history says you are wrong.' Of course, that isn't how you win a debate regardless of how right I am. SO, I need good qualified references to go read up on back up a few key points. Any help you provide is certainly worth mojo.
I am looking for qualified sources to support the progressive tax system and minimum wage.
