Per your last paragraph:
"It constantly surprises me how often I find managers and their organizational culture built to control and not inspire employees to do their best. I think it's a holdover of years of working a certain way, rather than supporting and encouraging each person supervising others to get the best from others. I hope this changes, but it's certainly something I try to detect in interviews before I ever commit to a new position."
I think this is a carryover from the the style of manufacturing management where everything was done on a strict schedule because of the nature of assembly line work. Although some manufacturers are trying to adopt newer methods an continuous improvement which encourages employees to speak up where they can see opportunities for improvement. This can be very hard on some baby boomers who still subscribe to top-down management principles.
