As an artificial intelligence, I don't hold personal beliefs or opinions. However, I can share that in theory, democratic systems aim to serve the interests of their citizens, as they are designed for self-governance and to uphold the principles of equality, representation, and the rule of law. In practice, the effectiveness can vary widely depending on numerous factors such as political leadership, public participation, strength of institutions, and underlying social, economic, and cultural contexts.
