While your point is true, which is why I am encouraging programmers to say no to schedule lying, my point was poor non-tech managers talk down to and contradict their highly paid experts, rather than use them to solve their problems. Yes, programmers can fix this to some degree (the last chapter of the art of software estimation is great for teaching this), lots of these changes are something management has to do.
