Mills explains that highly rationalized organizations, such as bureaucracies, have increased in society; however, reason as used by the individual has not because the individual does not have the time or means to exercise reason. Mills differentiates reason and rationality. Reason, or that which is associated with critical and reflexive thought, can move individuals closer to freedom. On the other hand, rationality, which is associated with organization and efficiency, results in a lack of reason and the destruction of freedom. Despite this difference, rationality is often conflated with freedom.
