I recognize that the majority of people on HN are progressives. So, I encourage you to think beyond your personal prejudices and recognize that our tax code stifles productivity and innovation. It's neither moral nor appropriate to work the 6 months of every year to pay the government, just to have the privilege of working the last 6 months of the year to try to pay your bills. Frankly, it's insane.
A flat tax is moral and would eliminate all of the monkey business (read: wasted productivity) that takes place, relative to tax planning.
