Only Fools and Horses was about a wide-boy, a street trader, a ducker and diver, from Peckham. There were and still are people like that. It was about an aspect of society at that time, a micro culture. Today it might be referred to as an underclass. I agree it didnt really reflect Peckham as a whole and the accents were a bit dodgy, particularly Rodney and Trigger, but some of the writing was very astute and reflected reasonably well a world I was familiar with while growing up.
