Despite the aim of communism to create a classless society elitism still exists in most communist states. The elite is usually composed of high-up party members, and 'heroes' of sport, industry, science and the arts; that is, those who are the best in their field and particularly those who have acquired international renown. The latter serve as propaganda abroad, the former provide propaganda for domestic consumption. Party members may rise in the hierarchy by denouncing their colleagues, but they themselves may be denounced and removed at a later date. 'Heroes' may also join the elite through conformism, particularly those in the arts and sciences, where innovative theories may be rejected by the party. The elite have greater wealth than the majority, and other benefits which include the possibility of more freedom and flexibility regarding restrictive laws. Although the idea of the worker is exalted in communist society, there are differences in pay for different occupations, and some countries even provide industrial incentives to management. Industrial 'heroes' may be the spokesmen or leading managers of a successful enterprise, and they may benefit more from the acclaim than the workers who should have equal share in it, but who are not credited individually.
