For half a century beginning with Franklin Roosevelt, there was a direct connection between the problems that afflicted American society and the remedies on offer from our democratic system. High unemployment? The New Deal, the World War II mobilization, and the postwar boom took care of that. Stagnant wages? With unions, growing productivity, minimum wage laws, and other regulation of labor standards -- American real wages tripled. Education? The G.I. bill, massive investment in public universities, community colleges, and later in public elementary and secondary education produced a better educated and more productive population. The exclusion of blacks from the American dream? A mass movement and a revolution in civil rights law made a big down-payment on redeeming the promise of Lincoln. I could go on, but you get the point. In the last century, democratic politics addressed real problems.
