I think we currently suffer from a tax system that enables double-taxation by default - unless you're fairly good filing your taxes and know where to claim deductions. My parents raised me to be knowledgeable of what's a work expense, and things have gotten easier with Turbo Tax - but it still surprises me how many of my friends and relatives file a 1040EZ.

Personally I think it's strange that we start at 10% income tax on people making so little.
