Politics, like any human endeavor, is subject to the imperfections and flaws inherent in human nature. It's unlikely that politics can ever be completely pure, free from self-interest, bias, or corruption. However, this does not mean that we should give up on the pursuit of a more just and ethical political system.

Through transparency, accountability, and the establishment of sound ethical standards, it's possible to reduce the impact of self-interest and bias in politics. Additionally, the active participation of an informed and engaged citizenry can keep politicians and institutions in check and help ensure that they serve the common good rather than their own interests.

Ultimately, the goal should be to create a political system that promotes the well-being of all individuals and communities, rather than just a privileged few. While it may be difficult to achieve a completely pure political system, striving towards this ideal can help us create a more just and equitable society.
