There was a time when the very wealthiest paid a substantial portion of their income in taxes, "Those were the years of the greatest middle class prosperity in America," says Author Sam Pizzigati. This inequality did not come with out a struggle and over the past 30 years it has slid backward toward the early 20th century American plutocracy. As tax day approaches perhaps we should remember the struggle against inequality and "be as bold as our predeccesors."

Pizzigati is the author of The Rich Don't Always Win: The Forgotten Triumph over Plutocracy that Created the American Middle Class, 1900-1970.
