For centuries, peddling goods in the market has been the most traditional venues to earn money. This is where retailers come in. They can be a business or person that sells goods or services directly to the consumer, with the aim to make a profit. The method may have changed over the years but the concept remains the same as retails can do business in the town's center market or in the web. The only thing that dramatically changed is the amount of money raked in by the modern day peddlers. Among the thousand billionaires around the world, some hundreds have made money through retail of products that range from groceries, fashion and everyday staples as well as the necessary services. The world's richest retailers take a significant spot in the list of the most affluent people in the world and they work behind brands like L’Oreal, Zara, Trader Joe’s and, of course, Wal-Mart. Zara's Amancio Ortega is the richest of them all even though Wal-Mart has the strongest showing. This makes the Walton family of Wal-Mart as well as Liliane Bettencourt of L'Oreal, and Theo Albrecht and family, to name a few as some of the most successful in the retail industry. They are often considered the lucrative executives who set the pace in the business and are well compensated for their efforts.
