yes. I presume government is charging ticket for travel. More pople means more money for government. If people are traveling without ticket, catch them and penalize them. Now when government is making money, they should make more tracks, should make metros, should put more trains, subs / tubes for public tranportation. That way government makes more money and then more infra structure. SOlution should not be to cut the population to reduce infra structure burden.
If trains are overcrowded, its failure of government and they should be reminded by the people. However leaders passed on blame to a specific section of people.
