at relieving the unemployment created by the country's precarious economic situation. The policies were popular because they forced out of the retail sector of the economy those foreigners, especially Lebanese, Asians, and Nigerians, who were perceived as unfairly monopolizing trade to the disadvantage of Ghanaians. Many other Busia moves, however, were not popular. Busia's decision to introduce a loan program for university students, who had hitherto received free education, was challenged because it was interpreted as introducing a class system into the country's highest institutions of learning. Some observers even saw Busia's devaluation of the national currency and his encouragement of foreign investment in the industrial sector of the economy as conservative ideas that could undermine Ghana's sovereignty. The opposition Justice Party's basic policies did not differ significantly from those of the Busia administration. Still, the party attempted to stress the importance of the central government rather than that of limited private enterprise in economic development, and it continued to emphasize programs of primary interest to the urban work force. The ruling PP emphasized the need for development in rural areas, both to slow the movement of population to the cities and to redress regional imbalance in levels of development. The JP and a growing number of PP members favoured suspension of payment on some Foreign Debts of the Nkrumah era. This attitude grew more popular as debt payments became more difficult to meet. Both parties favoured creation of a West African economic community or an economic union with the neighbouring West African states. 1972 coup and background Despite broad popular support garnered at its inception and strong foreign connections, the Busia government fell victim to an army coup within twenty-seven months. Neither ethnic nor class differences played a role in the overthrow of the PP government. The crucial causes were the country's continuing economic difficulties, both those stemming from the high foreign debts incurred by Nkrumah and those resulting from internal problems. The PP government had inherited US$580 million in medium- and long-term debts, an amount equal to 25 percent of the gross domestic product of 1969. By 1971 the US$580 million had been further inflated by US$72 million in accrued interest payments and US$296 million in short-term commercial credits. Within the country, an even larger internal debt fueled inflation. Ghana's economy remained largely dependent upon the often difficult cultivation of and market for cocoa. Cocoa prices had always
