The SED emphasis on managerial and technical competence also enabled members of the technocratic elite to enter the top echelons of the state bureaucracy, formerly reserved for political dogmatists. Managers of the VVBs were chosen on the basis of professional training rather than ideological conformity. Within the individual enterprises, the number of professional positions and jobs for the technically skilled increased. The SED stressed education in managerial and technical sciences as the route to social advancement and material rewards. In addition, it promised to raise the standard of living for all citizens. From 1964 until 1967, real wages increased, and the supply of consumer goods, including luxury items, improved much.
