Talk:Next billionaire

Wal-Mart is the clear leader in retail, with about triple the sales of any other competitor. It grew voraciously over the last few decades by blanketing the U.S in superstores and acquiring subsidiaries abroad. With a strategy of everyday low prices and the economies of scale to ensure it could beat any competitor, the company was once unstoppable, offering the competitive moat that Buffett so values. From 2000-2010, revenue grew from $165 billion to more than $400 billion. However, in recent years, Wal-Mart's stampede has slowed.
