Chalo apki baat maani ki Zyaadaatar public Non AC Sleeper class prefer karti he aajkal. But WHY?
The actual reason you also know. IT is only due to less fare so on the place of calling that Most of the public Non-AC Sleeper prefer karti he, you may say that most of the public cheaper options prefer karti he.
And...
more... demands cannot be fulfilled if revenue generation is in negative, such problems can be resolved only by removing the negative part of revenue. This can either done by increasing price(fare) or cut down the supply for such product.
Mark my words, if fare of Sleeper classes will be increased to twice then after also no one will cancel there essential travel plans. It is only a fake narrative setup by few great economists. Those economists have already been failed when fare of Auto Rikshaw has been hiked by 5 times in last 20 years. No one started going by walk even when they cannot afford the fare of Auto .
