Did automotive start it, or was automotive just hit first? I don't know, and I think might take a while until we know. I have to agree that 9 months payment terms are unacceptable. That truck yards at warehouses and factories are full has more to do with bad yard management, or non at all. That is less a problem with JIT or procurement, instead it is a purely operational issue.
That us in SCM and logistics, incl. procurement, have tendency to push issues down to lower tiers is true. it is also true that logistics and transportation is offloading a lot on public infrastructure. Does it have to be that way? On the one hand, yes. Roads are public, railway lines more often that not as well (to an extent that is). That's what taxes are there for, because indirectly everyone if profiting from a running economy. Again, that is less the case in developing countries and should change. I also agree, and that is maybe even more important when it come to the environment at large, SCM should prioritize environmental and climate protection more, along with social standards. That won't happen so until it is financially beneficial to do so. This is a general issue with capitalism running rampant so. Chemical plants giving a shit about worker health and safety or the environment is as old as chemical manufacturing., just as an example.
