Excellent question. To bad so few are asking it.
I lived in Jerusalem in the 1970's. Back then it was perfectly safe to walk through straight through the Arab shouk in the Old City. All the Arab shopkeepers were making money as never before, and welcomed Israeli and Western customers. They were far more prosperous under Israeli "occupation" than they had been under Jordanian rule.
And it wasn't the Israelis that displaced them.
It was their own Arab 'brethren'.
