As it turns out it doesn’t actually cost that much on regular transit, there’s an AIRPORT SURCHARGE because it’s an “airport train”.
No wonder Americans don’t use public transit, even when the system exists it’s ridiculously difficult and expensive to use.
They didn’t say ‘‘not funded by any means’’ they said ‘‘free’’ meaning ‘‘free to ride’’ the upside of free to ride is that it’s accessible to everyone all the time. The funding for public services can come from a lot of different revenue, for instance ad space on the transit, concessions, taxes on luxury items, even state lottery systems.
