The kafala system isn't going anywhere so long as we can't tell these countries to take their oil and drink it. The same thing (i.e. "sponsoring" someone by capturing that person's passport and forcing low wage labor for any hope of retrieval) happened to those enslaved workers in Qatar, and then the Qatari women had the nerve to brag about how liberated they were -- that there was no housework to which they were shackled. Hmm, I wonder how many other problems they can outsource to the exploited world's poor?
