Seeing as many are obsessed with what other people earn/have, I see in today's paper that Peter Sutherland left 2 million in his will. Estate values are public information from the Probate Office.

The Indo is attempting an angle with the comment that Sutherland was once said to be worth 153 million. There's probably people delighted that by the time he died he was only worth 2 million. AFAIK this only covers Irish assets which could be a small part of a person's actual wealth. Also, assets held in joint names often do not need probate. Also, someone may transfer large amounts to family members before death, or shock horror, give large amounts to charity.
