A fair tax is a progressive income tax, not a flat tax. If you examine recent history, you will find that a steeply progressive income tax is associated with a more prosperous, more equal society. Then chief executives earned perhaps 40 times what the lowest paid employee was paid. Now chief executives earn 350 times or more what the lowest paid employee earns. Then the top tax rate was 91% and now it is much less. I say look at the results. We need to raise the top tax rate to 75% or thereabouts to fund a progressive agenda and to reduce the greed of the highly paid to increase their share of the economic pie at the expense of the 99%. Trickle down economics does not work. We should abandon trying to make it work.
