I don't think Israelis are less critical of corruption than people in Italy, France or America. Israel is special in a different way. There is a daytime Israel and a nighttime Israel. The first is self-confident, pushy and passionate, like other Mediterranean lands. It is hedonistic, materialistic and almost arrogant. During the nighttime, people are terrified, people are filled with existential dreads. These fears aren't baseless.
