Many Arabs became rich from selling land, worthless to them, to those strange Jews who actually thought it was valuable. Land that was considered by Arabs to be unusable were turned into gardens by the Jews - who then turned around and employed the Arabs.
Arabs from Syria and Transjordan, who stayed away from Palestine for hundreds of years, suddenly decided to move there - because those awful imperialist colonialist Jews were creating an economy where there was none.
Now, today, which Arab population in the Middle East enjoy the best living standards and the most freedom?
The ones who stayed in Palestine to live together with those horrible, racist, Zionist Jews in 1948 during the "naqba"!
