Tiebout argues that a consumer voter will choose a community to live in that satisfies his or her preference for public goods, and his or her choice to stay or leave articulates his or her demand for a public good . This model has limitations: the inability to be extrapolated to the federal level and the inability of low-income people to articulate interest and satisfaction. Nonetheless, it has been shown to take place on a local level, as seen in the article referencing Montgomery County. Those who work in Montgomery County would ideally like to live there, but due to higher utility costs have chosen to live in nearby counties that they likely believe offer a preferable utility cost for similar services. The same ideas of consumer voters are found in articles that refer to communities with age limits above 55 years. Adults who choose to move to these communities prefer public services designed for them rather than higher costs for community services they don't use. All articles illustrate the need for state and local governments to provide public services and the tension between high expenditures and the need to act autonomously or communally.
