KLM, I mean seriously, who are we kidding? Whether it's referred to as ghetto or gangster, it's the commonly held belief that those are synonymous (in most instances), again most instances, with black culture. It, IMO, is simply a PC way of avoiding having to say black. Truth be told, if "inner city" didn't also have that trait, it would be most correct to say "inner city culture." With the notion being that people packed on top of each other and who live in poverty, are more prone to commit crimes.
No, you may perceive it that way but black is not by default ghetto. Big difference between the two in the way a person carries themselves.
