A lot of what I knew about Walmart came from third party sources (activists, whatever), so I decided to go to a primary and read Sam Walton's book, and I must say it gave me a new appreciation and understanding for the vast machine that is Walmart. I highly recommend it:
Sam Walton has been dead for decades now, and many of his ideas (giving stock to employees, even store workers) made more sense for the early growth stages he oversaw than the company that exists today.
True, but I never said it was a book about today's Walmart, just that I found it interesting to learn about that company's history and that I recommend the book.
