I do think there are ways to increase wages significantly, even in a global era. But you have to take voters and consumers with you on this journey - and that involves a tremendous, and long-term, public education campaign.

The reliance on stereotypes is in part the result of a structural problem within the media. Most newspapers have a business beat, with a number of highly trained journalists who know how to cover companies, trading, the markets and so on. But almost none have labor reporters anymore, and to my knowledge, none have full-time poverty-beat correspondents. And all of this helps to render invisible the lives and the life stories of tens of millions of Americans.

You can't lift people out of poverty simply by tweaking the tax system, or by raising the minimum wage by a few cents, or by reducing student debt slightly. These might be necessary components of a larger anti-poverty program, but you have to accept they are pieces of a much larger puzzle.

Today there are a huge number of think tanks working on poverty-related issues; there are books written on the topic; and university centers being created to study poverty. But, at the same time, the media has a terribly hard time with this issue; it's very hard to convince editors and publishers to devote resources to complex investigations of the lives of America's poor. And, as a result, too often poverty is portrayed in stereotypes, in sound bites, in a few pat images rather than in its full Technicolor complexity and diversity.

Detroit is a fascinating place, because things are so bad there that the dystopia has almost become utopian. People know they can't rely on the state, that public infrastructure is broken, and they've taken their own measures. People are growing their own food and selling their produce to local stores and restaurants. It's certainly not a fix-all; Detroit's problems are too deep-rooted for quick-fix solutions. But it's a hopeful sign. Detroiters are crafting their own solutions rather than being passive in the face of the city's and state's actions and inactions.

One of the most durable successes of the war on poverty was to dramatically reduce the number of elderly poor in America. That's still true today. But, by contrast, child poverty has shot up over the last few years: A decade ago, about 16 percent of children in America were poor - which is a shockingly high percentage. But it's not as shocking as today, when we see that 22 percent of kids live in poverty.

As a country, Americans have to find a way to keep our cities solvent. If large numbers of cities no longer have the necessary tax base, we have to find federal methods to intervene. If we don't, there's a risk of dozens of cities simply being left to their bankrupt fates - and I can't see how that serves anybody's interests in the long run.
