Army of Wal-Mart
Here's an (maybe-not-so) interesting fact. Behind the U.S. Government, the largest employer in the United States is Wal-Mart with a stunning 1.1 million employees working at 1,409 Wal-Mart stores, 1,562 Supercenters, 539 Sam's Clubs, and 70 Neighborhood Markets all making $256 billion in sales last year.
That's a lot of people. If Sam Walton's family ever decided to put an army together to overthrow the government, it may have the resources to do so; that is if their employees were soldier material. Actually, many of them do have military experience having fought in World War 2.
