Talk about the ground reality and not the nonsense ok. The nonsense words and the same thinking of praising white horses by giving absurd logic is not fine at all. You in person might not come out of ac but there are majority of people in the country who cannot afford all their savings or earnings to enjoy third class ac for some hours and govt is liable to take care of them also that too essentially. Profit will be equivalent or say it will be way ahead then ur calculation for the white horse,if the above mentioned 50% vacant class (which in reality will be more) will be substituted by non ac class. This will maintain the balance ⚖️.
