Tax reform could be really simple. Flat tax, tax credits up to the federal poverty line so as to not regressively tax the poor. No exemptions, no deductions. No tax refunds, because you know exactly what you're paying right out of your check and you wouldn't start paying until you were above the poverty line. You're just done right off the bat. Tax investment income the same way. All income is the same no matter what the source.
Just a bit, man. Of course, there are the crazy internet libertarians who think taxation is actually theft, and that the majority can at no point force you ethically to participate in society. I'm not one of those. For me, it's a philosophy which seeks to answer, 'How can government, which is by nature a loss of autonomy, minimize it's negative impact while providing an appropriate level of function and service to its people?'
