The myth of scarcity in the arts is the long held belief that there's not enough X to go around. Where X represents one patrons, audience, venues, whatever. This myth creates a sometimes vicious competitive environment.
The myth is detrimental to both individual artists and the community.

Another reality check is that there is only a minuscule number (I've heard rumours that it is 1% of 1% of all artists) make a large amount of money off their artwork. And by large amount of money, I mean rockstar lifestyle. We could probably figure out who they are right now, ummm, Damien Hirst, Olafur Elliasson, maybe Jeff Koons and tangentially Christo & Jean Claude (tan. because they make money off sketches of their work). Am I missing anyone?
Here's the secret, everyone else is making money off alternative sources of income which are funding their work (teaching, speaking, working in the arts, etc). Now, there are probably quite a lot of artists who make a reasonable amount of money off their work (as opposed to the rockstar levels of money), mostly these are artists who can create easy to market & sell work, which, often is not even the work they would consider the most important or interesting. Like the e-bay and painting-a-day people (there's a lot of merit in these methods of funding). If you are doing large scale public projects (say a chalk line around NYC) then your funding might come in a small part from grants and individuals, but in a larger part from speaking opportunities, image rights and some amount of commodification. My painter friend is pursuing painting portraits as a means to fund his work, a couple of my other friends who create non-object based work subsist on teaching and occasional fellowships. It's a good idea to understand that you will be the biggest funder of your own work, so you should find something you can do to make money that will make you happy.
So, about how this community concept can help. It's quite simple actually, so simple in fact that there is a cliche already made for it: a rising tide lifts all boats.

Yes we should all be talking about money too. It empowers us all to know what people are paying for services and products so that we can price our own products and services accordingly. (For example, in my experience speaker fees can range anywhere from $200 [for local panel] to $1000 [for individual presentation outside NYC], and stipends for showing work that is documentary in nature [documentation of a project already completed] is about $300). It also helps us all present a more united front, sure there are lots of artists doing things for free (even I admit to that for a select situation), but the more we all ask for the money we rightly deserve, the more likely people will pay for it. The power of a positive no is a great thing.
So think about it, and figure out what you have to share with your fellow artists, and go out there and give that away (while simultaneously asking to be paid for your creativity).
