The real problem is revenues. The rich are using loopholes to wind up paying a smaller percentage than the middle class workers (remember Romney paying 13% on more than $20 million in income -- that's not uncommon at all among the top 1%, and especially among the top 0.1%). And then you have the corporations. They receive many billions in subsidies, while paying a lower share of taxes than at any time since the 1950s.
The Republicans, on behalf of their rich friend on Wall Street and in corporate boardrooms, have tilted the economic playing field to favor the rich. It is time to fix that. Call it "class warfare" or "income redistribution" if you want, but it's really just economic justice. We need to return to the time before "trickle-down" economics was put in place by the GOP in the 1980s -- a time when everyone in our society benefitted from a rise in productivity, and not just the rich.
