No doubt. Just about every country in that heavy Muslim region has high unemployment. Most countries have 10%+ unemployment and Gaza before the war has google saying 40-50%. A decent unemployment rate in western countries might be around 5% (give or take a bit). Now multiply that by 10x.
As I said weeks ago, its too bad the Hamas leaders care more about oppression and religious nutlording than helping the people and economy. Education and jobs works wonders. Make some money, have some purpose, keep busy. To be fair, just about everyone would go gonzo if the entire neighburhood had no jobs.
