See the response immediately below yours regarding poverty and crime rates in W. VA.^ An unintended consequence of an economic ghetto. If you run the numbers on what those men can make doing legit jobs full time and then having to take care of themselves and a family, you will see that it is impossible. You make about $10-20K a year doing the jobs normally available to them. Conversely, for selling a bag of crack, you can get a whole week's wages in 45 minutes.
So, what you're saying is, the "inner city culture" is one of drug-dealing?
I'd concur with that. Is it an unintended consequence of "an economic ghetto"? There we'd disagree. The "economic ghetto" and its drug-culture are an unintended consequence of The Great Society™ in combination with the War on Drugs™. The violence isn't due to the economic ghetto - they come as a team. I invite you to read this: "It's most important that all potential victims be as dangerous as they can."
