Political Dynasties

Mail Today has carried a comprehensive story on political dynasties in India. Another article carried in the edit page today argues that power ought not to be given on a platter to lateral entrants to politics. The author's critique of Shashi Tharoor making it to the MEA, right after his maiden contest and success in the Lok Sabha polls, without any prior exposure to politics, is interesting. Is there scope for political/legal/constitutional reform to discourage dynasties and lateral entrants to politics from making political contest in a democracy uneven?
