Start-up Nation: The Story of Israel's Economic Miracle makes a good case. [0]
I have also experienced this - in addition, rampant nationalism is an issue when dealing with Israeli companies, in my experience (5 different customers, similar problems..)
Where I think Israeli tech startups get most of their mojo, is desperation. Their culture involves so much struggle and effort .. and I think the reaction to it at a personal level, results in the laziness, non-team-playing, political problems.
In my experience, it's been the opposite. They like to play office politics, focus on keeping work off their plate, and they're not really team players.
I may just have a bad sample of Israel tech workers, though.
