The Zionist Offer to Buy Palestine in 1901

And people think Zionism started int he 1940s.

How on earth is the above evidence on anything?
The Jews bought land sold to them, which is a known fact and made the land prospereous, for then Arabs to also migrate to an area which was seen as barren with hardly many people living within the area.
If the land was sold, then they own the land, its as simple as that, because nobody else wanted it.

Introduction and summary - It appears that while Zionists had purchased about 6-10% of land, depending on how it is figured, the actual share of Arab holdings  was probably much lower than is stated and the share of government land was much higher. There was never a systematic survey of Palestinian lands. The inability of Zionists to acquire land was due in part to the fact that the mandate government violated the conditions of the mandate and tended to make government land available at cut rate prices to Arabs rather than to Zionist purchasers. The high figure of Arab ownership was apparently generated by counting all village and town land and other dubious claims as "Arab," though  under the terms of the mandate, Jews and the Zionist organization should have had a share in ownership of public land. None of this land was ever purchased by any Arab, but it was assigned as "Arab land."   Arab "ownership" was further inflated by chaotic registration policies that legitimized squating after the fact, and by counting land as "owned" when in fact it had been leased. Most of the land in Palestine registered in the name of individuals was not held privately, but was registered as "Miri" holdings, that gave the user the right to the usufruct of the land. The land itself remained property of the government. If the land lay fallow for three years, it should have reverted to the government. There was an unknown but large area of such unused land that was not reverted to government use because of the wishes of mandate personnel to please Palestinian Arabs.   
The Arab Fellah had been steadily displaced or "dispossessed" from the land by factors other than Zionist purchases. These included gradual industrialization and urbanization which was taking place throughout the Middle East and was accelerated by Zionist settlement, as well as the poor administration and unfair nature of archaic Ottoman land laws. The number of landless Arabs was apparently deliberately exaggerated in the Hope Simpson report by misrepresentation of statistics.
The Jewish Agency and other Jewish organizations and individuals had purchased perhaps a third or even half of the available arable agricultural land in in what would become Israel by 1948, and the Jewish sector produced twice as much in tax revenues as the Arab sector, though it accounted for only a third of the population of Palestine. Nonetheless, it is difficult to make a case that Zionist settlement affected the Arabs of Palestine adversely. Arab standard of living rose steadily in Palestine except for drought years and the self-inflicted misery of the Arab general strike. Jewish land purchases affected fairly small numbers of Palestinian Arabs who had been engaged in extensive agriculture and usually found better paying employment or better land. The Arab population of Palestine grew steadily. There was no evidence that Arabs were leaving Palestine for economic reasons.

Zionism, Palestine land purchases and dispossession of the Arabs

The Zionist goal of purchasing land in Palestine both under Turkish rule and under the British mandate was in part frustrated by acute lack of funds, and by various regulations imposed by the Turks and the British, despite the fact that the British were supposed to be facilitating the construction of a Jewish National Home under the terms of the mandate. A chief complaint used by the Grand Mufti Hajj Amin Al Husseini to incite rioting, especially in the Arab Revolt was that Zionist land purchases were "dispossessing" Palestinian Arabs, who would soon have no means of livelihood.  Given the lack of orderly statistics on land ownership and displacement, and an objective criterion for such displacement, these claims, echoed by modern writers as well, are difficult to investigate and evaluate. They have been elevated to a dogmatic claim that Arabs were being dispossessed systematically in Palestine, but there is in fact little substantial evidence for this prior to 1948 (See Zionism and Its Impact).
A study by Kenneth W. Stein (Stein, Kenneth W., The Land Question In Palestine, 1917-1939, Univ. of North Carolina Press, 1984 and Stein, Kenneth W., Palestine's Rural Economy, 1917 - 1939, Studies in Zionism, Vol. 8, no. 1 (1987); pp. 25 - 49 )  concluded that Palestinian Arab fellahin were being systematically displaced from the land, but that this was an ongoing process that had begun in Ottoman times, and was not related to Zionist settlement. Rather, he attributed it to the archaic land laws, the Tanzimat reform of those laws which favored the rich, competition from inexpensive imports and the depredations of World War I, which had ruined Palestinian agriculture and put many poor peasants hopelessly in debt. The eagerness of owners large and small to sell their land no doubt increased as the prices that others were willing to pay increased. As in all countries at the beginning of the twentieth century, agriculture became less and less capable of supplying a livelihood and could not compete with other land uses and labor opportunities. Greedy landlords found ways to evict tenants and sell the land or put it to more productive uses, subverting laws intended to protect tenant farmers. The land was usually not sold to Zionists or Jews.
Different statistics have been advanced by each side to prove whatever point they wished to prove at any given time, and actual statistics of land ownership and utilization are very scarce and non-systematic.
About 17%-20% of the land area that was British Mandate Palestine is now estimated to be arable, the total area being 26,625,600 metric dunam (a metric dunam is 1000 square meters; the Turkish dunam was somewhat smaller)  between the Jordan river and the Mediterranean. Cultivable land was estimated at about 6.4 million dunams out of 26 million. In the 1930s, Maurice Bennett, seconded to Sir John Hope-Simpson (who was to prepare the Simpson report) made far different estimates of arable land, which are given below
