The Communist regime created another social group at the bottom rung of the ladder. This group was composed largely of elements of the upper classes in existence before 1944. The tribulations of this class had by 1970 reduced it to a small minority, some members of which were still interned in forced labor camps. It was actually a class of outcasts, discriminated against politically, socially, and economically. Most of the members of this group were used as so-called volunteer laborers on construction projects and in other menial tasks, and their children did not enjoy the same rights to higher education and other opportunities open to the other classes. Discriminatory measures against this class continued to be taken in the late 1960s; in 1968, for instance, the government passed a law prohibiting them from receiving money remittances or food and clothing packages from their relatives and friends abroad. The Communist assertion of the existence of only two social classes did not correspond to the real class structure that prevailed in the country in 1970. In fact, there existed different classes and gradations of rank and privilege, beginning with an upper class, composed of the Party elite, leaders of the state and mass organizations, and the leading members of the armed and security forces. The top Party elite itself was composed of two distinct social groupings, the higher group consisting of the Political Bureau (Politburo) of eleven regular and five candidate members and the chiefs of the Directorates of the Central Committee the lower group being made up of the rank-and-file members of the Central Committee. Family connections played a key role in the composition of the Politburo in 1970. The top three families were those of First Party Secretary Enver Hoxha and his wife Nexhmije, who headed the Directorate of Education and Culture in the Central Committee; Prime Minister Mehmet Shehu and his wife, Fiqrete, who headed the top Party school; and Party Secretary Hysni Kapo and his wife, Vito, who headed the politically and ideologically important women's organization. General Kadri Hasbiu--minister of interior, head of the security forces, and a Politburo candidate member--was a brother-in-law of Mehmet Shehu. Similar family relationships existed between the other Politburo members. About half of the sixty-one members of the Central Committee were also related.
