There should be a minimum qualification to enter politics in India because not everyone is well suited to work in politics. You should require a certain amount of knowledge and leadership experience in order to enter politics in India, just as we have requirements needed to work in politics in the United States.
India is a free country and anyone can aspire to any job. Yet in politics, there are no minimum standards. There should be at least some kind of minimal educational test when a politician signs up to run for office. The test needs to change every cycle to prevent cheating, but some of it should include basic information as to how the Indian government works. Such tests prevent fraud and scandals in the future.
