A bunch of right-wing baloney. The transportation systems in NYC are what make that city even possible. It is very easy for an uncreative bean-counter to look at the price tag of public transportation systems and then not be able "add up" all the long term benefits of having a city where people and businesses can thrive and get around and that are enjoyable and aesthetic.
If you really want to talk about "gouging" the taxpayer, instead look at highway funding and regulations that practically enforce sprawl by requiring parking spaces, and multi-lane streets through urban cores.
