I don't think it's a "conspiracy theory" in the traditional sense (although I do admit that my post was slanted a bit that way). I'm fairly certain it is as Crito said, "unplanned [and] unorchestrated". And there's no need for conspiracy: simple human nature in the aspects of politics and pettiness can easily explain it - it doesn't matter if you can prove what is more productive or cost effective, management ("owners" or their representatives) will continually push for more leverage and control over their workers, until they experience pushback, profits be damned.
