In 1985, Sam Walton began a program designed to stem the 'tide of communism' in Central America by promoting capitalism and privatization. His efforts included funding scholarship programs to bring Central American students to Christian universities in the United States, hoping that exposure to American capitalist and Protestant Christian values would dissuade them from becoming involved in communist movements.
In 1998, Walton was included in Time Magazine's list of 100 most influential people of the 20th Century. Walton was honored for all his pioneering efforts in retail in March 1992, when he received the Presidential Medal of Freedom from President George H. W. Bush.
Forbes ranked Sam Walton as the richest man in the United States from 1985 to 1988, ceding the top spot to John Kluge in 1989 when the editors began to credit Walton's fortune jointly to him and his four children. (Bill Gates first headed the list in 1992, the year Walton died). Wal-Mart Stores Incorporated also runs Sam's Club warehouse stores. Wal-Mart stores operate in Mexico, Canada, Argentina, Brazil, South Korea, China, Germany, Puerto Rico, and in the United Kingdom (having taken over Asda).
He left his ownership in Wal-Mart to his wife and their children: S. Robson "Rob" Walton, John T. Walton, Jim Walton, and Alice Walton. Rob Walton succeeded his father as the Chairman of the Board of Wal-Mart, and John was a director until his death in a 2005 plane crash. The others are not directly involved in the company (except through their voting power as shareholders). The Walton family held 5 spots in the top 10 richest people in the United States until 2005. Two daughters of Sam's brother Bud Walton, Ann Kroenke and Nancy Laurie, hold smaller shares in the company and are also billionaires in their own right. If alive today, Sam Walton would be the world's wealthiest person, twice as rich as Bill Gates. Today, some people say about him: "He was a good guy, except if he was running you out of business."

Governance
Wal-Mart is governed by a thirteen-member Board of Directors, which is elected annually by shareholders. S. Robson Walton, the eldest son of founder Sam Walton, serves as Chairman of the Board, and H. Lee Scott, the Chief Executive Officer, serves on the board as well. Other members of the board include Aida M. Alvarez, James W. Breyer, M. Michele Burns, James I. Cash, Jr., Douglas N. Daft, David D. Glass, Roland A. Hernandez, Jack C. Shewmaker, Jim C. Walton, Christopher J. Williams, and Linda S. Wolf.
Notable former members of the board include Hillary Clinton (1985-1992)[27] and Tom Coughlin (2003-2004), who also served as Vice Chairman. Clinton left the board prior to the 1992 U.S. Presidential Election, and Coughlin left the board in December, 2005 after pleading guilty to wire fraud and tax evasion for stealing hundreds of thousands of dollars from Wal-Mart. On August 11, 2006, he was sentenced to twenty-seven months of home confinement, five years of probation, and ordered to pay $411,000 in restitution.
