There is probably some truth in all of that (although I strongly disagree in some specific points), but also consider that if "management" is incapable to convey their own value, and to cooperate with "engineers" in a non-antagonizing way, maybe they share some of the responsibilities in the divide... esp. if they are supposed to be "management" and take care of rational things (business value being an obviously rational one...) while engineers are basically... playing with their toys?

I don't understand how your vision of things is not also contributory to a strong divide.
