How much credit should the Occupy movement get?

Glimmers of Occupy Wall Street will surface this week in some cities as activists join rallies for workers’ rights, as they do every year on May Day.

Occupiers won’t show up en masse, but they will hold signs and chant, railing against a variety of social and political issues. That includes an issue that has gone viral: income inequality.

How much credit Occupy deserves for propelling the issue onto the political agenda is a matter of debate.

But Occupy ignited a global conversation. Protesters popularized the concept of income inequality and made their rallying cry of “We are the 99 percent” part of the global lexicon.

Many Occupiers remain frustrated that the gulf between rich and poor remains vast.
