Kerala is not industrial hub. Gujarat is one of the largest. GDP growth is 11%-12% consistently. GDP close to 200 Billion $. Infrastructure development highest in India and many more. Also, Gujrat has active role in national politics. Kerala is ruled by Left communist (worst party in India and less important in national politics) and then Pseudo Congress with allies 2 religious based party (ML + KCP).
Kerala need not be and Industrial Hub..........If you think only industrialization can improve economy then i have nothing to say.
Kerala Earns a Lot of Revenue Through Tourism and IT
Show me the Activeness of Gujarat in National Politics( AK Antony & Vylar Ravi all are from Gujarat)
