the state both socially and economically. For example, to overcome discriminatory labor practices, Governor Herbert H. Lehman created the Committee on Discrimination in Employment in 1941 and Governor Thomas E. Dewey signed the Ives-Quinn Act in 1945, banning employment discrimination. The G.I. Bill of 1944, which offered returning soldiers the opportunity of affordable higher education, forced New York to create a public university system since its private universities could not handle the influx; the State University of New York was created by Governor Dewey in 1948. World War II constituted New York's last great industrial era. At its conclusion, the defense industry shrank and the economy shifted towards producing services rather than goods. Returning soldiers disproportionately displaced female and minority workers who had entered the industrial workforce only when the war left employers no other choice. Companies moved to the south and west, seeking lower taxes and a less costly, non–union workforce. Many workers followed the jobs. The middle class expanded and created suburbs such as the one on Long Island. The automobile accelerated this decentralization; planned communities like Levittown offered affordable middle-class housing. Larger cities stopped growing around 1950. Growth resumed only in New York City, in the 1980s. Buffalo's population fell by half between 1950 and 2000. Reduced immigration and worker migration led New York State's population to decline for the first time between 1970 and 1980. California and Texas both surpassed it in population. New York entered its third era of massive transportation projects by building highways, notably the New York State Thruway. The project was unpopular with New York City Democrats, who referred to it as "Dewey's ditch" and the "enemy of schools", because the Thruway disproportionately benefited upstate. The highway was based on the German Autobahn and was unlike anything seen at that point in the United States. It was within of 90% of the population at its conception. Costing $600 million, the full project opened in 1956. Nelson Rockefeller was governor from 1959 to 1973 and changed New York politics. He began as a liberal, but grew more conservative: he limited SUNY's growth, responded aggressively to the Attica Prison riot, and promulgated the uniquely severe Rockefeller Drug Laws. The World Trade Center and other profligate projects nearly drove New York City into bankruptcy in 1975. The state took substantial budgetary control, which eventually led to improved fiscal prudence. The Executive Mansion was retaken by
