In 1976, UK wages were amongst the lowest in Western Europe, being half of West German rates and two-thirds of Italian rates. In addition, while educational opportunities for working-class people had widened significantly since the end of the Second World War, a number of developed countries came to overtake Britain in some educational indicators. By the early 1980s, some 80% to 90% of school leavers in France and West Germany received vocational training, compared with 40% in the United Kingdom. By the mid-1980s, over 80% of pupils in the United States and West Germany and over 90% in Japan stayed in education until the age of eighteen, compared with barely 33% of British pupils. In 1987, only 35% of 16- to 18-year-olds were in full-time education or training, compared with 80% in the United States, 77% in Japan, 69% in France, and 49% in the United Kingdom. There also remained gaps between manual and non-manual workers in areas such as fringe benefits and wage levels. In April 1978, for instance, male full-time manual workers aged 21 and above averaged a gross weekly wage of £80.70, while the equivalent for male white collar workers stood at £100.70.
