When's the last time you heard of someone kidnapped and forced into construction work?
It's a whole other topic, but this is happening to the Nepalese in Qatar. Nepalese men are promised high salaries, adequate housing, health, transportation, etc. When they arrive they are placed in labor camps, have their passports confiscated, charged for their flights, housing, "orientation fees", make pennies a hour and forced to work hours on end in dangerous conditions. Those who speak out are thrown in jail. Many are dying on the job.
Not comparing one thing to another, but unfortunately slavery is still alive and well in many forms.
