"In the beginning of the 20th century when Jews started campaigning for bringing more Jews into Turkish, then British Palestine, the process often went like this: Jewish community or a wealthy individual buys a plot of land from a Turk owner. Turks never worked that land themselves, and used to hire local Arabs to do the agricultural labor. Jews would not rehire Arabs after acquisition, instead, they used the newly bought land to create jobs for more Jewish immigrants."
I have never heard this one before. And it doesn't really track with the populations that were actually there in 1900. The Arabs at that time, in that place were largely nomadic herders. The largest city in the region at the time only had about 30,000 people in it. And it had been sometime since the Ottomans actually had any real political control of the area. So perhaps it did happen to some extent, but to claim it was the driving force in creating the conflict seems very ahistorical to me. Especially considering the 200 years of Pograms that preceded it. The real reasons for the conflict happened between 1500-1700, and have more to do with trade and the collapse of the Silk Road than Zionism.
PS The Ottomans outlawed selling land to Jews in about 1900. So a lot of the sales weren't recorded so perhaps you have a point, IDK.
