If trickle-down economics worked, we would not have four food banks in Kensington and Chelsea.

Health and the Income Inequality Hypothesis.

In 7.81 square miles of vaunted black community, the 850 square feet of Dum Dum Donuts was the only place in the "community" where one could experience the Latin root of the word, where a citizen could revel in common togetherness. So one rainy Sunday afternoon, not long after the tanks and media attention had left, my father ordered his usual. He sat at the table nearest the ATM and said aloud, to no one in particular, "Do you know that the average household net worth for whites is $113,149 per year, Hispanics $6,325, and black folks $5,677?"

"For real?"

"What's your source material, nigger?"

"The Pew Research Center."

Motherfuckers from Harvard to Harlem respect the Pew Research Center, and hearing this, the concerned patrons turned around in their squeaky plastic seats as best they could, given that donut shop swivel chairs swivel only six degrees in either direction. Pops politely asked the manager to dim the lights. I switched on the overhead projector, slid a transparency over the glass, and together we craned our necks toward the ceiling, where a bar graph titled "Income Disparity as Determined by Race" hovered overhead like some dark, damning, statistical cumulonimbus cloud threatening to rain on our collective parades.

"I was wondering what that li'l nigger was doing in a donut shop with a damn overhead projector.

Do not really like rich people, as they make us poor people feel dopey and inadequate. Not that we are poor. I would say we are middle. We are very, very lucky. I know that. But still, it is not right that rich people make us middle people feel dopey and inadequate.

Income inequality is troubling because, among other things, it means that many people in our society don't have the opportunities to advance themselves.

Inequalities at the bottom of the US wage distribution have closely followed the evolution of thee minimum wage: the gap between the bottom 10 percent of the wage distribution and the overall average wage widened significantly in the 1980s, then narrowed in the 1990s, and finally increased again in the 2000s. Nevertheless, inequalities at the top of the distribution - for example, the share of total wages going to the top 10 percent -- increased steadily throughout this period. Clearly, the minimum wage has an impact at the bottom of the distribution but much less influence at the top, where other forces are at work.
