The Vietnam War hastened the modernisation and Westernisation of Thai society. The American presence and the exposure to Western culture that came with it had an effect on almost every aspect of Thai life. Before the late 1960s, full access to Western culture was limited to a highly educated elite in society, but the Vietnam War brought the outside world face to face with large segments of the Thai society as never before. With US dollars pumping up the economy, the service, transportation, and construction industries grew phenomenally as did drug abuse and prostitution. The traditional rural family unit was broken down as more and more rural Thais moved to the city to find new jobs. This led to a clash of cultures as Thais were exposed to Western ideas about fashion, music, values, and moral standards.
