The fixed income case is absolutely trivial to solve by just giving them a stipend or discount card, which is obviously what they do in NYC.

The people who drive into a city to work should either pay for access to the city's economy and infrastructure that supports their job (and the entire surrounding region's suburbia), or they can get a job in their own community, or they can take a form of transit with fewer negative externalities on the city. Not that hard to understand.

It's not "absolutely trivial" and it's not "obviously what they do in NYC".

It is a convoluted system of city and state tax credits, partial discounts, etc that you must do every year. Not only do you have to file additional forms as part of your tax return, you must also recertify your disability annually.

And if you are simply low income, you can apply and then you receive a 50% discount after your first 10 trips into the city each month. If you are going into the city 2-3 times a week, you receive no discount.

While the number of options for receiving relief can be large/varied/complex, each individual program is definitely not complex.

Low-income: Show your tax return <$50k/yr or show your enrollment in a public assistance program.

Disability: Get your disability assess annually or show enrollment in the already-existing disabled-people transit assistance programs.

Not sure what you think is non-trivial about either of these?

You seem to be avoiding the point that to get a discount you must travel into the city by car more than ten times a month and those first ten times are full price.

And then you must pay 50% of the price after that. Then, in April, you may get some tax relief.

This is a good system and trivial in your mind? Because the average low income or fixed income person can just float that money for a year and then maybe get some of it back?

And you can't even do it if you've moved recently. If all of your documents don't have the exact same address you are out of luck. If you've moved since you filed your taxes and your address on your car registration is your old address you're out of luck until you file your next taxes and update your registration.

And then you have to mail it all in and just wait until you get a response. And if it's denied you get to start the process again. And then next year you get to do it again.

This isn't "trivial". Trivial is submitting your social security number, VIN, drivers license, and address.

You're mixing two distinct relief systems.

The standard low-income relief program does not entail any tax credits or fronting any money. It's just a discount attached to your EZPass.

A different relief program gives you a post-facto tax credit.

These are two different systems. One is easier for one group, the other is easier for a different group.

Sure go make it more trivial. No complaints there!

They already pay substantial taxes out of their income to the city they work, in most places. They already are paying for access.

Empirically demonstrated by their continued decision to live outside of the city and commute into it, they believe they are getting more value than they are paying in via whatever tax scheme the locale has in place.

You'll know they're paying their fair share when the arbitrage actually stops, but taxing non-resident earnings so aggressively to stop it produces way more negative side effects and regressive taxation effects than congestion pricing does. That's why congestion pricing is a good idea and 90% taxes on non-resident incomes is not (not to mention the ease of enforcement).

Living in NYC is really expensive. Those that earn a lot can do so. Those that have families frequently cannot.

It's not "arbitrage" to commute from a place you can afford to a place you can't. Being middle class isn't an arbitrage play.

That is quite literally arbitrage.

People with families aren't often willing to accept the living conditions they'd need to in order to live in NYC while paying market prices. So they arb and get suburban living conditions with urban employment.

The cost of their decision to do that is mostly borne by the respective communities (home community loses economic productivity and then city community bears increased infrastructure consumption).

We would know there's zero arbitrage when zero people did this. Which again, I don't think is the goal to shoot for. But simply asserting you have some god-given right to make this arb indefinitely at zero cost is a losing argument.

So what?

You didn’t say they should pay as much as they are willing to pay. You said they should pay.

They are paying!

Your new goal is that nobody can afford to work in the city except residents, but that is an objectively dumb idea, and certainly has nothing to do with a “fair share.”

I certainly did not declare that as a goal, lol. I said that you'll know you have eliminated the arbitrage when people no longer do the arbitrage. This is a simple description of reality and not a normative claim.

First, in most cities people don't pay income taxes to the cities they work in but do not reside in. At least in the US this is not typical.

Second, the position that people should pay to reduce their negative externalities does not necessarily imply the view that they pay nothing today. It implies they ought to pay more.

If someone pays for entry to Disneyland, steals a t-shirt, is a valid defense that "they paid" when they bought the ticket? No, obviously not. Does demanding that they pay for the t-shirt imply that they did not pay for a ticket? No, obviously not.

No you said, "You'll know they're paying their fair share when the arbitrage actually stops.” It might not have been intentional, but you communicated clearly that people should be charged more until they are unwilling to work inside the city and live outside. Otherwise they are not "paying their fair share.”

Nevertheless, NYC is the only city I’m aware of in the USA that has congestion pricing, and I’m shocked to find that non-residents who work there do not pay income tax to the city. I live in OH and have to pay an income tax to the small city I work in even though I’m not a resident of said city. I thought it was more common.

You're jumping from "it's unfair that people can do X" to "the goal is to prevent all X."

I, as a realist, believe in systems with flex. As our very own patio11 put it: the optimal amount of fraud is nonzero. Here, the optimal amount of unfairness is nonzero. Or stated another way: the cost of eliminating all unfairness would not be worth it.

The assumptive jumps are not necessary here!

Fine, let’s take it for granted that you don’t want to all of it. But the clear implication of saying that people aren’t paying their fair share is that they generally should. So your ideal may not be 0, but it is (even by your own analogy), close to 0. It’s like saying the goal is to end fraud, and you bring up the technicality that actually the cost of ending all fraud is not worth it. Ok, but the ideal is still no fraud, and nobody is confused about the general goal being to get rid of as much of it as we can cost effectively.

So now I’m honestly asking, are you or are you not arguing that the general goal is to end people "not paying their fair share” (which you equate to living outside of the city you work in)?

Also can you please explain why you believe that “fair” is measurable in this way? Can you give another example of something where a common person would use a similar definition of fair? I think that your definition of fair means stores without dynamic pricing are unfair, which seems crazy to me.

Uhh... I've already stated explicitly that's not a goal. I don't know why you're fixated on something I never said or even implied.

I don't think this should be described as a tax. It's paid access to a scarce resource, no different from a parking garage charging people to park. In this case it just happens to be a government-owned resource, but that doesn't make the price a tax.

If you're worried about poor people, the right move is to price things properly and then give assistance to those who need it, rather than giving away scarce resources to everyone for free.

A government fee or whatever you wish to name it is still a tax.

Didn't the city already charge tolls on the bridges and tunnels in and out?

A road isn't a scarce resource. You can't deplete it.

So when I go buy rum at the local liquor store, the price on the shelf is actually a tax? That's not what the word means.

Land is a scarce resource. Roads require land. Charging money for access to land is extremely common.
