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.

Ronald Reagan, and before him, Richard Nixon, and before Nixon, a slew of conservative politicians going back through American history, have played to the idea that the great majority of poor people are somehow "undeserving," and being undeserving, merit at best very limited, oftentimes deeply coercive and humiliating, government interventions to better their finances. That narrative isn't about to disappear overnight; but it strikes me as being like a weak gruel - there's no sustenance in it, no heft behind the argument.

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.

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.

To really tackle poverty, politicians, activists, academics will all have to think outside their boxes, will have to start developing much more integrated approaches to these problems. And a large part of this will involve working out ways to push for living wages. Partly this will involve re-empowering the union movement, which has been massively weakened in recent decades. Partly it will involve a willingness to restructure tax codes to penalize companies that don't provide basic benefits and decent wages to employees.

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.

When I talk about an "empathy bank," I don't mean literally opening up a bank and putting in deposits. What I mean is that the more we can, as individuals and as members of a community, empathize with, understand the pain and uncertainty economic crisis causes other people, the more we lay the groundwork for political change.
