Easton's Political System model
1. Changes in the environment affect the actors prompting the generation of demands addressed to the government
2. The government filters the numerous demands it receives
3. Demands must be driven by supporting factors to gain significance and legitimacy for government action
4. Support may come in the form of the citizen's tax payment, obedience to laws, and participation in government-led activities
5. Decisions are made in the form of policies for enforcement and feedback from the public
