Let me put this in language even YOU can't misconstrue or misunderstand. 
The lack of a reliable, cheap train service hurts the entire city. There isn't a single person here whose life has not been terribly harmed by this and we can see it's starkness because we HAD a cheap, reliable train service quite recently.

This proves two things: 
1) That is possible for a government run train service to be both cheap and reliable - it was for decades.
2) That it's WORTH the subsidies. It's meaning an extra 2 hours a day in traffic (an hour each way) effectively 25% more of my time sacrificed for work than before (even if my boss doesn't get the benefit). So the cost to me, every year, of the trains not running - is 25% of my annual salary ! That's more than HALF as much as I spend in taxes  IN TOTAL that the railways were saving me until recently.
I promise you that's at least 100 times more than what I contribute to the subsidized tickets.

The subsidiy was PROVABLY cheaper for us all
