The poverty we see in America is now too widespread, and too complex, for easy fixes. But I do think we can reimagine many of our institutions and can create new ones in ways that would be effective. We could, for example, create social insurance systems, similar to social security, such as that we went through in 2008-9. We could create a financial transaction tax, oil profit taxes and a fairer estate tax system, and we could plow much of the revenue raised from these into job training programs, into better education infrastructure, into an expanded Earned Income Tax Credit.

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.

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.

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.

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.
