from aggression such as J. William Fulbright (Arkansas), and Martin Luther King Jr. (Georgia), as opposed to Lyndon Johnson (Texas) and Secretary of State Dean Rusk (Georgia), but the war was generally more supported in the South. Mid-20th century to present In the years and decades following World War II, the old agrarian Southern economy evolved into the "New South" – a manufacturing region with strong roots in laissez-faire capitalism. High-rise buildings began to emerge throughout the mid-to-late 20th century, in skylines of cities such as Atlanta, Charlotte, Dallas, Houston, Memphis, Miami, Nashville, New Orleans, San Antonio, and Tampa. The former main economic base that focused largely on agriculture, such as cotton production, was phased out with mechanization technologies and economic diversification of new industries. There were 1.5 million cotton farms in 1945, and only 18,600 remained in 2009. By 2020, many Fortune 500 companies were headquartered in the South including Texas with 50, Virginia with 22, Georgia with 18, Florida with 18, North Carolina with 13, and Tennessee with 10.

Today, the economy of the South is a diverse mixture of agriculture, light and heavy industry, tourism, and high technology companies, that help serve both the national economy and global economy. State governments in the South recruited corporate businesses to the "Sun Belt", promising more enjoyable weather and recreation, a lower cost of living, skilled work force positions, minimal taxes, weak labor unions, and a business-friendly environment. With the expansion of jobs in the South, there has been migration of people from other U.S. regions and immigrants from other countries, increasing the population and political influence of southern states. The newcomers and growing population within the region helped in displacing the old rural political system, built around courthouse cliques from the late 19th century through mid-20th century. Many suburb areas became the base of the emerging Republican Party within the region, which became dominant in presidential elections by 1968, and in most state politics by the 1990s. With the economy growing into other job sectors during the mid-to-late 20th century, farming was less emphasized as before (and the remaining farmers more often specialized in things such as soybeans and cattle, or citrus
