The failure of the first Barack Obama administration to really deliver on a new War on Poverty and a new language to explain these societal challenges in some ways provided the fuel that led to the Occupy Movement a few years later. And, while Occupy was a somewhat transitory phenomenon, many of the activist groups that emerged during this period are still out there, and still working on reshaping the political debate around taxes, around welfare, around government assistance to the poor, around debt relief for students, and so on.

Big cities like New York are thriving, economically, culturally, in terms of real estate values, and by a slew of other measures. Yet, at the same time, much of the country has been utterly hollowed out. In California, where I live, affluent coastal cities such as San Francisco and the Silicon Valley hubs have lower than national average unemployment, higher wages, higher tax bases. Meanwhile, there are inland counties in California where there's still nearly 20 percent unemployment.

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.

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.

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.

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.
