Transit is very heavily subsidized by taxes. In the US, the least money losing system is BART which covers 70%+ of it's operating (but not capital) expenses through fares.
By Republican logic, public libraries "lose money". So do a lot of public services.
But it's not about some shitty private equitymoney extraction. And it's not lost money.
Public transit is already substandard to driving, and should be free. And it'd be a way to reduce congestion too. But no, it "loses money".
The point is it should be free. Public roads are free.
