The degree of a society's level of inequality endorsed by the followers as much as by the leaders.
Power Distance Index (PDI) is a measure of the degree to which a society's members are willing to accept and expect unequal distribution of power within their society. In other words, PDI measures the degree of a society's level of inequality endorsed by the followers as much as by the leaders. PDI is one of the dimensions of Hofstede's cultural dimensions theory, which compares national cultures across six dimensions: power distance, individualism-collectivism, masculinity-femininity, uncertainty avoidance, long-term versus short-term orientation, and indulgence versus restraint. Therefore, the correct answer is The degree of a society's level of inequality endorsed by the followers as much as by the leaders.
