that's just awful. I had no idea.
Lots of the rugs from Pakistan and India are made by children. If you want to buy a rug I think it's probably better to get an antique (despite the concern with developing nations selling off thier cultural history and heirlooms) or a machine made one. The ILs gave us a rug for our wedding present - it's beautiful but I don't like it because I always feel anxious about where it came from and who made it.
