What changes have been made to Wharton Group managers since 1980s?

In the early 1950s, discount sales just appeared, and Wharton was in his forties. He is already rich and runs 15 stores in Kansas, Missouri and Oklahoma. They are all traditional small town shops with relatively high prices. Wharton actively studied retail experience, and the whole family did not forget to visit local shops when they were on vacation. When Herbert Gibson, an exotic hairdresser, opened a discount store in Wharton's small town, Wharton realized that this was the future business trend. 1On July 2, 962, Wharton was 44 years old and opened the first Wharton supermarket. In the same year, S·S· Cleskey also opened his Kama Supermarket, and F·W· Woodworth and Dayton Hudson also opened similar supermarkets or chain stores. Discounted goods have changed the American way of life. Once the discount was allowed, Wharton began to reform for the rest of his life, reducing the cost between shops, manufacturers and middlemen, and making commodity prices fall again and again. In this way, the gross profit is minimized and the sales of Wharton Supermarket continue to grow. Wharton opened a shop wherever he could find an opportunity. Sometimes he studies the terrain on a low-flying plane. If he finds a piece of land at the junction of several towns, he will buy a vacant lot there and build a Wharton supermarket, so that his supermarkets can be spread all over the country.
