Whether the object (either privilege or a burden) has been taken on voluntarily, earned, gifted or inherited doesn't matter IMO - the idea is that in either case the responsibility to the object lies on the subject. For example - you own a factory with 100 workers. It is a privilege to lead and conduct such a business. At the same time, it is a burden that needs to be carried - the business must be ethical; workers, contractors & partners paid on time, it must be profitable (or at least potentially profitable in the future), etc.
