It makes no sense for the City to devote the amount of resources they do to buldiing and maintaining this inherently private good, and then to just give it away to some individuals (but not all) for free.
I don't know whether it makes economic sense, I'm not an economist, but it sure as hell makes
political sense. We live in a society that is, even here, very car-centric, whether we like it or not. People get so up-in-arms whenever parking spaces (free or otherwise) get taken away because it makes life (usually marginally) more difficult for everyone who relies on a car. It imposes a cost when a lack of parking precludes the ability to have and use a car. Plenty of people are perfectly fine with this (I don't drive and have spent the best part of the past fifteen years commuting solely via the T), plenty of people aren't. Not everyone can go without a car.
There's something of a difference, I think, between free public parking, metered public parking, and resident permit parking. Free public parking is the most objectionable, because it encourages people who could afford to pay for parking to park in spaces that could otherwise be used for those less able to, or that might not need to be there at all. Metered parking brings revenue for what is effectively temporary private rental of a public space. It's still essentially a regressive tax but it also provides the benefit of enabling access (especially to places in transit droughts) to businesses and services while returning at least some of the cost to the government in question. And in a car-centric society there's going to be economic cost if no one can patronize a business either because there's no parking or because it costs too much to park there. Resident parking, whether free or not, is a public service to residents that reflects the fact that lots of people
need a car and therefore need a place to put it. My sister lives in Jamaica Plain, and a lot of the places around her don't have driveways or garages; it's not going to go over well if the government's policy is, sorry, if you want to live in this place you can't have a car because there's literally no place to park it (until someone comes along and builds a private garage to gouge locals, anyway).
Public space should be open for public use. We shouldn't hand over public value to a select number of individuals who jump through a bunch of expensive hoops in order to be allowed to use expensive public resources while excluding others from using them.
We hand over public value to select individuals all the time. And either I don't understand or just don't agree, but how is this not "public space open for public use"? It's
public parking (resident parking being a specific section of the public). We, the state, collectively hand over millions upon millions of dollars to the MBTA; figures are a little hard to come by but even the HRT lines the fares only cover something like 60% of the cost of running them, which represents an enormous subsidy in the form of taxpayer dollars going specifically to select individuals in the form of transit riders. It's not a direct equivalent, especially because (street) parking is a far more limited resource.
I mean, if all you're trying to argue is that you think that free parking is inherently problematic and wrong, then I suppose I understand. I don't agree, because it is a definitional public good in that it's provided by the government for general use. (I live in a suburb with ample parking and a bit of sprawl. Half the businesses downtown would go out of business if the city parking lots got shut down - hell, quite possibly if they even charged - because access would be bloody impossible without somewhere to park.) Even resident-permit parking is a public good for residents who a.) need a car and b.) may not be able to afford privatized parking. It's perfectly fine not to like that that public good is provided, but I can't say I agree that it's
not a public good at all.
