Final answer:
Sam Walton founded Wal-Mart and Sam's Club, adopting a 'high volume, low margin' business model. Bill Gates, Steve Jobs, and Jeff Bezos, while notable entrepreneurs, are not associated with the foundation of these retail chains.
Step-by-step explanation:
The founder of Wal-Mart and Sam's Club is Sam Walton. He was a pioneer in buying in extremely large quantities and selling goods at low prices, which helped establish Wal-Mart as a major retail force. This strategy is known as a 'high volume, low margin' business model, where a company sells more products at lower prices, hoping to make up the reduced profit margin through higher sales volume.
On the other hand, Bill Gates is the founder of Microsoft and made his mark in the technology industry by developing software for personal computers. Steve Jobs co-founded Apple, which is known for its innovative electronics and software products. Lastly, Jeff Bezos founded Amazon, which began as an online bookstore and evolved into a massive online retail and technology giant. None of these individuals are directly associated with the foundation of Wal-Mart and Sam's Club.
