Well the conspiracy theorists will have a field day with this.
Why do these people flock to the United States and the European Union? They are against the western culture and ethics, and yet every year hundreds of thousands of immigrants from the Middle East ends up in the EU and the US. And what is more surprising is the attitude of the Western governments towards these people. They are encouraging the immigration.
They have to encourage it. Their economies would collapse otherwise. Too many lazy stupid white people in those countries who wont or cant do the jobs so immigration is needed.
