Interest groups are relatively universal; they exist in different regions in different countries, and some even operate on an international level. Interest groups have promoted and also been the reason for, significant changes in different places, and on various topics. Though all interest groups exist for different reasons and serve different purposes, they all have some common advantages.
Some of the advantages of interest groups include:
- Promoting democracy; interest groups promote, and protect the interests of minority groups, or the minority. These groups give those involved, including minority groups, freedom to express their opinions, which suggests their rights are protected and promoted, and that democratic principles are in play. For example, these groups ensure that doctors have a license, but that the accreditation criteria stays fair, and represents everyone, including those who received education outside of the country, as well as those who may be less able
- Creating real change; power in numbers is a real thing. Lobby groups can organise people to enact change or come together with a common cause. The unity that these groups provide creates a louder voice than any one individual, regardless of their role or title. Even changes on a smaller level are noticeable; because, as people join the group, they become more and more informed, and well versed, in areas critical to the issue or topic
- Positive solutions to various problems; interest groups come together, because each individual member has identified, and wishes to solve, a problem, rather than complaining, or continuing to be part of the issue. The groups can advocate, or make the change required, to have an impact that is felt well beyond just the interest group
Overall, interest groups can create a meaningful, and impactful, change, and make a positive solution, to a mutually agreed upon problem or issue.
