QCM..
Don't you think the American government is trying to stop that flow? And if you try to compare the U.S. to the U.A.E. in this respect, just look at the recent amnesty the U.A.E. government has offered. Many workers (although certainly not all) will use the amnesty to LEAVE the U.A.E. to return to their home country. In the U.S., the government there is being pressured to give amnesty to illegal workers so most can STAY in the U.S.
"MEXICANOS", as you call them, go to extreme measures to get into the U.S., legally or not.
And by the way, the report is based more on the effort's of a specific country to prevent/stop human trafficking, not the extent of the problem itself.
Your comparison is hardly fair.
