Slavery was just outlawed in Mauritania in 2007(!)
(You'll have to listen to this BBC story to understand the title of this post.) I get so angry when I think about stuff like this. On the other hand, I think about whether some girl in a Chinese factory working 14 hours a day so I can have cheap electronics or a migrant worker from Mexico picking strawberries for below US minimum wage is right. I think what makes it not worth worrying about for most people is that the information about working conditions has been lost (e.g. I don't know that my $2.99 strawberries were picked by someone getting paid $2.50 an hour). Recovering this information and exposing it (along with making it easy for people paying below minimum wage to head to prison for a year would do some good).
I love me some good ol' cognitive dissonance.
