Not realistic. I am not saying you can't get rid of those lobbies, but you can't get rid of human nature which is greed.
As long as a system open to all party, ideologies, religions, colors of skin, races, gender, ages, there will be difference, and people will naturally fight for resource. That's human nature.
There have to be some one, some system on top of all interest, suppress the conflicts to certain level, decrease tension, and serve the common good. Which in Chinese, we call it Heaven 天。
There is no easy solution, or political system which can be installed in any societies, or countries. It must grow organically on their social soil, culture.
What failed India is they installed a Christian liberal democracy inherited from western culture and value, but India can NOT adept and digest.
