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.
Because that’s the foundation and definition of capitalism. The market will provide (as long as there’s profit to be made).
Not saying it’s right though.
That’s not the definition or foundation of capitalism, it’s the definition of a market economy.
The foundation of capitalism is a system where investors can pool small amounts of money together on big projects, to share risk and reward. Historically to fund trading ships on their way to the indies.
So it destructures ownership, which has a million ripple effects on the organization and economy.

In the context of “Why do Americans think everything has to profit?”, then the point is that the train is considered only for the profit it can make, and not for the environmental etc benefits. This is a result of the market economy as you rightly state (and private ownership of transportation).
