Opinion polls continually show that corruption (in all sectors of society) is the main complaint of the people. Currently, hospitals, schools, police, and social and legal institutions are constantly affected by bribery, cronyism, and nepotism. However, the Communist Party of China still asserts a monopoly on exposing corrupt officials and businessmen, and critics accuse the party of selective punishment. Analysts say the authorities are reluctant to pursue senior figures and their allies and punishment comes in the form of political purges rather than genuine law enforcement.
