According to Ha'aretz, Ariel Sharon is the wealthiest Israeli PM in the state's history:
"In sharp contrast to conventional wisdom, Israel's wealthiest prime minister is not one of the has-beens. It's not Ehud Barak who makes millions consulting and running the lecture circuit and who built a luxury home in Kfar Shmariyahu. Nor is it former prime minister, Finance Minister Benjamin Netanyahu, a close associate of some of the world's wealthiest Jews and who has advised several local technology companies.
Actually, it is the present premier, Ariel Sharon - the farmer from Kfar Malal - who is the wealthiest prime minister to serve Israel ever. According to an appraisal ordered by Haaretz, Sharon's primary asset, Sycamore Ranch, is now worth $11.3 million or a cool NIS 50 million. The value of the farm has risen virtually miraculously since the early 1970s, when he paid only $500,000 for it."
Apparently "people will always pay more for the home where the prime minister used to live." I wonder how much Hitler's bunker is worth.
