Rupert Murdoch - why would an extremely rich man promote policies that benefit extremely rich people?

Rupert Murdoch, the founder of a global media empire that includes the News Corporation and its Fox News Channel subsidiary, is an extremely wealthy man.

A March 2009 news story claims he is worth $3.38 billion (Australian):

The Daily Telegraph - March 25, 2009 03:58pm

RUPERT Murdoch's wealth has halved but he is back on top of the annual BRW list of Australia's top 200 executives.

In a year when the total wealth of executive in the list was more than halved, News Corp chairman Mr Murdoch was first with $3.38 billion, compared with $7.9 billion last year, BRWmagazine's third annual Rich Executive list found.

 What is the primary economic message conveyed by Murdoch´s media empire?  Isn´t it that we should pursue policies that benefit wealthy individuals and corporations?  Is anyone surprised?
