We need well educated politicians to come out with laws and policies in the country keeping in mind the long term effect on the nation. For that you need to be well read about the global socio-economic and political stuffs. Having information and knowledge helps you to analyze the situation and come to a more thoughtful solution or decision weighing the pros and cons of it. In our country, we have seen decisions made by politicians out of sheer ignorance and hunger for vote and power. Reservations and many such policies in education were arm chair policies which have dragged and paralyzed the country. It was just made to get votes. Lack of educated politicians in opposition also hampers the situation as there is no genuine opposition to oppose such bizzare propositions.
illegal constructions and so many developmental projects lack a visionary and do harm in long run. Country needs expertise in people and politicians for a constructive development of the country.
But I do agree that politics is also a service option along with career option. In fact I would put it across as a career option that is meant for service of nation and people. People who have service option should be allowed to enter politics through proper channels. They can enter at entry level as workers and then groomed and educated to a minimum qualification before they can contest election and come into mainstream politics. This will streamline so many shortcomings. Also put the message clear-- you can not take a shortcut.
