From the Left to the Right:

Why is there more a phenomenon of people migrating from the Left to the Right and not from the Right to the Left: in the West and in the Arab world?  Simply, because there is more of a financial reward of the first kind of migration but not the second.  The only example of Right to Left that I can think of is David Brock, the Clinton's Hit Man, who was horrible as a rightist and is horrible as a leftist.
