The most important--and unfortunately the least debated--issue in politics today is our society's steady drift toward a class-based system, the likes of which we have not seen since the 19th century. America's top tier has grown infinitely richer and more removed over the past 25 years. Few among them send their children to public schools; fewer still send their loved ones to fight our wars. They own most of our stocks, making the stock market an unreliable indicator of the economic health of working people. The top 1% now takes in an astounding 16% of national income, up from 8% in 1980. The tax codes protect them, just as they protect corporate America, through a vast system of loopholes. Incestuous corporate boards regularly approve compensation packages for chief executives and others that are out of logic's range. As this newspaper has reported, the average CEO of a sizeable corporation makes more than $10 million a year, while the minimum wage for workers amounts to about $10,000 a year, and has not been raised in nearly a decade. When I graduated from college in the 1960s, the average CEO made 20 times what the average worker made. Today, that CEO makes 400 times as much. Trickle-down economics didn't happen. Wages and salaries are at all-time lows as a percentage of the national wealth. This ever-widening divide is too often ignored or downplayed by its beneficiaries. A sense of entitlement has set in among elites, bordering on hubris.
