That, in a nutshell, is the story of the free enterprise system. Salespeople built our nation's economy. The inventions of Thomas Edison, George Westinghouse and Alexander Graham Bell would have been useless if people hadn't learned about them, bought them and used them.
Mass production is impossible without mass selling.
That's what manufacturers' and wholesale sales representatives do. Manufacturers' representatives are in business for themselves and work directly with manufacturers. Wholesale sales representatives work for wholesalers-companies that sell products in large quantities to retail stores and industrial and commercial users. Both types of salespeople interest customers in their companies' products and take orders. Increasingly, they also act as problem solvers, making sure their customers get the goods and services that are right for their business.
