Looser are the peoples of those states. Unfortunately Bengal and Kerala will always remains as 'farmer' and 'unemployment' peoples states since all opportunities of growths are clipped on beginning stage itself.
Politicians very well know that once state become rich and peoples have enough employment opportunity they never get the ‘followers’ and criminal to execute their agendas and sustain their power.
Peoples are so stupid never realize when one industry closedown due to some political agenda is really screwing up their future. This will be a ‘case study’ for any industrialist/corporate person to not choose those places as an investment destination. If TATA suffer like this in INDIA think about another foreign or Indian investor.
