The National Low Income Housing Coalition has put together the map above (h/t NYT) that underscores the real impact of inequality in our society. In a sentence, it shows the the rent is too damn high and the wages are too damn low.
In fact, there is no state in the country where a 40-hour minimum-wage worker can affordably rent a two-bedroom apartment (at fair market rent). In fact, in about half the states, even two 40-hour minimum-wage workers can barely afford that. This is why, pre-crisis, many activists focused on the fact that minimum wages are not living wages (and thus, the Democrats successfully raised the minimum wage after taking Congress in 2007). Regardless of that change, the minimum wage is worth less than it was in 1968. The value of the minimum wage over time actually captures the general stagnation of lower-class wages over the last 30-40 years.
And, one personal anecdote on this: when I was at Notre Dame, before I knew much about economics, my big cause was a living wage campaign on campus that turned into a more general pro-labor and pro-union effort. We organized and organized without getting very far, and the recession hit as I was graduating, and so little has happened since. However, what first drew me in was the simple notion that a worker at a Catholic institution (or anywhere for that matter) should be able to support their family working 40 hours. Maybe that is no longer part of the social contract, and we should just focus on employment. When the economy recovers, though, the ranks of the working poor will still be huge.
