India does not shut down for extreme heat because the Indian citizen has been trained to treat suffering as a national virtue.
Sit in a 45°C classroom. Commute in a metal box. Work outside till your brain starts cooking. Stand in election rallies, court corridors, factory floors, construction sites, coaching centres, government offices, traffic jams and railway platforms like this is normal human existence.
Then clap because some neta gave a revdi, invoked caste pride, promised vishwaguru status, or shouted about some civilisational issue that will not reduce the temperature of your skull by even 1 degree.
Human life has very little value in a poor country where people themselves have been conditioned not to demand basic dignity. The state treats citizens like serfs because citizens keep proving they are willing to live like serfs.
