I don't think everyone paying the same income tax is what people usually advocate for, but everyone actually paying the full share of the tax. I think a flat 20% above a certain rate is probably the most 'fair', but what needs to change is remove most loopholes that exist now. So everyone above a certain income level pays the same proportion of their income. Of course the tax base ends up really top heavy, if you earn most of the income, you pay most of the tax. That seems fair to me.
