政治腐敗
Political corruption is the use of powers for illegitimate private gain, conducted by government officials or their network contacts. Forms of political corruption include bribery, cronyism, nepotism, and political patronage. Forms of political patronage, in turn, includes clientelism, earmarking, pork barreling, slush funds, and spoils systems; as well as political machines, which is a political system that operates for corrupt ends.
