The Post-Employee Economy
Fifty years ago, the four most valuable U.S. companies employed an average of 430,000 people with an average market cap of $180 billion. This year, the four largest U.S. companies employ an average 120,000 people with an average market cap of $334 billion. The titans of 2011 have twice the the value of their 1964 counterparts with a quarter of the employees.
