Missing in this parable: All the Type 1 workers getting out their pitchforks because Type 2 worker put them out of work, leaving them with no safety net and no useful skills in the new trench-based economy.<p>Nor is the fact that because Type 2 worker demonstrated how to solve the problem other villages will now be competing for the same water source. Creating political tensions that could lead to war ("over water" :).<p>Then there's the problem of too much wealth being held by Type 2 resulting in a village tax base that can't afford a war ("over water"). Type 2 sees the writing on the wall and moves his wealth overseas where the village can't touch it and declares that, "everyone should be thankful!" for what he's done. They no longer have to carry buckets of water, after all.
