I can't tell if you're intentionally being obtuse or not. The point of the original comment was that "Pareto-style" reasoning here is ridiculous: the engines and wings do 80% of the "work" in an airplane, but you can't remove the rest and expect it to still fly. You can't really quantize work inside of complex systems (like airplanes, or corporations) in this way; adjacent sub-threads in this thread explain why.
