> And progressive taxation.
Point of order: I'm taxed the same on my one-millionth dollar of income (assuming the same source) as Jeff Bezos is.
... I just don't have a one-millionth dollar of income to tax, but if someone wants to shift things toward equality rather than equity I'll happily accept donations toward that end. To make things more equal for Bezos and to strike a blow against equity, naturally.
