*Exit, Voice, and Loyalty: Responses to Decline in Firms, Organizations, and States* is a 1970 book by Albert O. Hirschman.
> members of an organization, whether a business, a nation or any other form of human grouping, have essentially two possible responses when they perceive that the organization is demonstrating a decrease in quality or benefit to the member: they can exit (withdraw from the relationship); or, they can voice (attempt to repair or improve the relationship through communication of the complaint, grievance or proposal for change). – wikipedia 
> The general principle, therefore, is that the greater the availability of exit, the less likely voice will be used. However, the interplay of loyalty can affect the cost-benefit analysis of whether to use exit or voice. Where there is loyalty to the organization [...], exit may be reduced, especially where options to exit are not so appealing [...]. Loyal members become especially devoted to the organization's success when their voice will be heard and when they can reform it. – ibid.
