Michael as Saver
Michael is a saver. He has put a large chunk of the money he receives in taxation into a supernnuation fund. He has employed several funds managment companies to watch over this next egg and make it grow. When the babyboomers reach retirement and have to be supported by a shrinking workforce, the fund will be there to make up the shortfall, and Michael will kick in as saviour.
Michael has established his fund, because he believes that people cannot be trusted to prepare for the future. He has decided to save for them. Michael believes that if the fund was returned to those he took it from, they would just eat drink and be merry (because tomorrow they die, I presume) and the opportunity brought by our current prosperity would be lost.
In a world without the true saviour, maybe people do need Michael to save for them.
