For a tax to be fair.. everyone must pay it (even if they get the entire amount back in pre-bate), .. it must be visible (so we all know what our government costs, ... it must be broad ..(no way to avoid). Reagan gave us a broad, semi-flax (three bracket) tax but look what happened .. it eroded.
I do not think there is any way to erode the Fair Tax.
I also love not having the IRS in my affairs.
