Protitutes - You can see Vietnamese at Joo Chiat area, China, Indoesians and Malays at Geylang and also some at Farrer Park area. Are thy neccessary in Singapore?
As in Singapore, there are hundreds of thousands of foreign workers in Singapore, so the many Singaporeans "know" that without the gals, these workers would go around raping or molesting Singapore girls and girls would stop wearing short pants, skirts and scantidly. Singapore would be tarnished in the international community and Singapore police would have a difficult time controlling these hundreds of thousands of foreign workers and only how many police officers?
But these would brood social ills too, as many young teenagers would go to these red light districts to settle their "needs" and other Singaporeans would make their extra money there by selling their bodies.
So how? To seriously limit protistution or to allow many protitutes to hang aroung in these red-light districts - the legal and illeagal ones.
