This is a detail from a massive mural at the Detroit Institute for the Arts. While Rivera affords an heroic vision of American labor, it would be a mistake to neglect the current travails of American workers. Harold Meyerson lays out some of the problems in his strong lament for labor at The Washington Post. And this story at In These Times and this one at The Nation make a set of points that overlap with Meyerson. The problems, of course, reflect the current depression; but they also reflect the fact that successive administrations in Washington - and the courts and agencies spread across the country - have failed to enforce basic aspects of labor law. In other words, the problem is political.
