Increase the cost of public transportation while you also cut service.
This could have been avoided (or at least somewhat mitigated) by imposing a toll on the Harlem and East River bridges. Some Democrats, though, opposed that measure, because they don’t think drivers should have to subsidize public transportation. I’ll just quote Baratunde:
Wrong. You SHOULD tax drivers precisely to subsidize public transit. That’s how it works. You tax the bad, evil, planet-melting crap to encourage a less apocalypse-inducing lifestyle. We tax smokers to subsidize health care, and we should probably tax short-sighted, incumbent politicians to subsidize the campaigns of thinking people who will run them out of office.
