The Wire's creator David Simon gave an address which is excerpted in the link below and appeared in the Guardian. Simon is skeptical of Marxism, as I certainly am, but the following passage shows his view that Marx got it right on how unfettered capitalism can be destructive: "I'm not a Marxist in the sense that I don't think Marxism has a very specific clinical answer to what ails us economically. I think Marx was a much better diagnostician than he was a clinician. . . . [H]e was really sharp about what goes wrong when capital wins unequivocally, when it gets everything it asks for."
Simon argues that the blooming of our middle class came because neither those with capital nor those with labor won all their arguments. He also argues that profit is the wrong metric by which to measure our economy's health. I include this link to keep and study his reasoning.
