The worst floods in Mumbai's memory has triggered off a blame game. While the slum-dwellers have been blamed for their illegal constructions, it is the trio comprising the political class, the developers and builder lobby as well as the corporate sector that is largely to blame. For long, town planning has been skewed in favour of more buildings and concrete infrastructure with the result, as so crucially revealed by the recent disaster, that the more urgent issue of repairing and modernising the city's outdated drainage system has been neglected.
