Honestly, I think that this is a time for all prostitutes to think twice. Internet is very important in our days. Many different companies create video chat software for adult sites. By the way one of such software http://www.streamingvideosoftware.info/ . Everybody can have it home. And this is much easier and really saves to work from home with your computer then to be anywhere on the street and wait for client. You never know who you will meet; more over the weather is not very good all the time. Also think about viruses. New technologies can help those girls to save their health and sometimes even live. Also girls can meet really rich guys who will become their client for many years and will come back again and again, in case of the working on the street you may not a such chance.
