There is enough blame to go around. Some of it inevitably attaches to those responsible for the death of that reputation, the Left Front, which opened up a space for the sort of agitation that drove away Ratan Tata, and gave it its methods. Much also attaches, as Tata was at pains to point out, to the current user of those methods — to Mamata Banerjee and the motley coalition of know-nothings and do-gooders that she pretends to lead. In the absence of security for ancillary units, for ordinary workers, Tata could leave — because in today’s India, other states will fall over themselves to be more welcoming, to create a secure place for Tata Motors. Bengal is once again living in a past, where there are no options for people that have invested in them. A door to its future has just closed.
