"SEX WORKERS"- Are the days of forced prostitution long gone?

Its proving very hard to establish reality from the perception of reality the media draws upon.
Two years ago channel 4 continually broad casted documentaries on the increase of prostitutes and their middle Eastern European pimp of a boyfriend on the London streets. They showed footage and convincing interviews of forced prostitution, rape and even called it "modern day slavery".
Last week, channel 4's documentary "Working as an Escort" depicted strong, independent and English speaking women on how much they enjoyed their chosen carrier.
Surely its not the same work description; Or is it possible that when a quick money making scheme is frowned upon they blame it on the foreigners, immigrants and non-English speakers but when a sexy spin is given to the "escort business" by the TV series "Secret Diary of a Call Girl" staring Billy Piper the credit goes to the English.
