This week's encore broadcast of Moyers & Company (check local listings), begins with a report on striking extremes of wealth and poverty on display in California's Silicon Valley. Facebook, Google, and Apple are minting millionaires while the area's homeless -- who've grown 20 percent in the last two years -- are living in tent cities at their virtual doorsteps. These are the human faces of economic inequality. Later, Bill is joined by writer Sherman Alexie. Born on a Native American reservation, Alexie has been navigating the cultural boundaries of American culture in lauded poetry, novels, short stories, screenplays, even stand-up comedy for over two decades. He shares his irreverent perspective on contemporary American life, and discusses the challenges of living in two different cultures at the same time -- especially when one has so much dominance over the other. "I know a lot more about being white than you know about being Indian," Alexie tells Bill.
