In the dynamics of an iron triangle what benefit do interest groups provide to friendly bureaucratic agencies?

In the dynamics of an iron triangle, interest groups provide valuable support to friendly bureaucratic agencies by offering resources such as funding, expertise, and political backing. This collaboration helps agencies secure their objectives and implement policies more effectively. In return, interest groups gain favorable regulations or government actions that align with their interests. This mutually beneficial relationship enhances both the agency's capacity to operate and the interest group's influence in the policy-making process.
