The socio/communist movement has proven this. The Arabs by their tradition are communal in their society. This explains their extreme envy of the West. We see this envy factor in our country where "soak the rich" is a rallying cry for the left.
I also read that they do not believe that interest should be charged (or paid, depending which side of the loan you are on) on loaned money. That has got to really cramp your ability to raise capital and run a business.
