Agricultural produce is a strongly limiting factor on how good human life can be - the most important process we run. To give kids a rudimentary insight into the mechanics and economy of it is - to me - clearly a more important lesson than understanding an oil rig.

I don't disagree - but energy, mining, and forestry are also fundamental parts of the economy (with transportation, construction, and manufacturing on the level just above those), and if we're talking about giving kids a rudimentary insight of the mechanics and economy of this big system in which we all live, I don't see any reason to stop at agriculture.
