We're pretty out of whack at the moment. Let's assume for the moment we do all of the following: Progressively increase taxation on higher incomes. Tax capital gains at income rates. Lower corporate tax rates to induce innovation and repatriate offshore money Give everyone universal healthcare We'd still have pretty massive wealth inequality. It'd probably take (no math done) at least a few decades to fund everything to their logical points, as well as other social financial instruments -- not to mention actually getting around to reparations (which would significantly help not only wealth inequality but racial wealth inequality). You could probably sunset the Wealth Taxes after, say, twenty years and see if people roll it over if still needed.
