Robert McChesney in the Monthly Review (Nov. 2000):

In the 1940s, most medium- and large-circulation daily newspapers had fulltime labor-beat reporters, sometimes several of them.

Today there are less than ten fulltime labor reporters in the media; coverage of working-class economic issues has all but ceased to exist in the news. Conversely, mainstream news and "business news" have effectively morphed over the past two decades as the news is increasingly pitched to the richest one-half or one-third of the population.
