Changes in management thinking are suggesting that the real value of companies lies in its people. As much as 70% according to Paul Strassmann. You can test that by looking for example at Apple's share price performance in recent years. It seems the market believes Steve Jobs has the Midas Touch. That could be demonstrated by this week's launch of the iPhone and the impact it had on the market. The launch completely upstaged CES.  

However - there could yet be a backlash against Jobs. While he is seen as a creative and design genius, he has been exposed as a control freak and quite prepared to ride roughshod over others - including his own shareholders through the options back dating scandal.
