That's exactly what happens. The "travel agencies" that give this false information are like scouts, they constantly hunt for poor people who will fall for this. It is common sight at the New Delhi international airport to see workers going abroad in batches. Most of these people have never been out of their villages before. They sit on the floor in groups and are moved through the security procedure by a "manager" like a herd of sheep. They all seem happy and filled with hope.
It's a global scam where the idea is to make money out of slavery and ensuring profit to every person in the chain, from the sheikh to the so called "travel agencies" and take away the right to complain from the only people who may complain.
