Child Trafficking and the Internet

Chatting with a seatmate on a flight, I learned she was attending a conference, hosted by Shared Hope International, on domestic trafficking in minor children. Naively and optimistically, I asked if this problem has been diminishing.  No, quite the contrary.  Why?  The reason appears to be economic, having to do with technological change and technology transfer.  With the internet, it is much easier to engage in transactions — nothing needs to be done face-to-face, thus reducing the risk to traffickers. Also, organized crime is getting involved since the trade is so profitable, as at-risk children can be traded repeatedly (unlike an ounce of crack cocaine). With some modifications, an established drug network can be used as a child-sex network.  Disgusting, horrible, and a negative side-effect of technological progress.  (HT: JM)
