>>With a flat tax, they will be.
IMHO it's more likely that people will form ranks on partisan lines and then cherry-pick statistics to support the party line, forcing compromises and manoeuvrings that invariably benefit those who can fund the most furore or drag the country closest to the brink. That's what happens now. In addition, my experience has been that the most concentrated wealth stays within privileged families for generations and/or is otherwise geared to defer tax, often forever.
"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
