Especially here in Britain we are brought up to be deferential, to defer to the views of those of higher status and authority.
But the problem is that deference is automatic, it is based on role and status and assumes that role and status are a sign of skill, wisdom and trustworthiness.
Respect is different. It is earned. It comes about as a result of consistent behaviour.
Without respect society falls apart.
Without deference, it gets the chance to rise to a higher standard.
