Since I make money through magic, you would think I cared more, yet I don't. I make money by writing books, teaching an online course, giving lectures and workshops, providing magical products and services, and actually using wealth magic itself to generate money through investments, assets and so on. You either want to buy what I am selling or you don't. I respect your decision either way.
Still, I have a few thoughts:
Isaac Bonewits gets brought up a lot because he has been an advocate for paid pagan clergy for a long time, and because he has been known to send around e-mails to the pagan community every now and than asking for money. I like Isaac, but you ain't gonna get paid for being clergy in a religion that has no congregation. Its just simple math. Besides you had ample opportunity:
You graduated with a BA in Magic and Thaumaturgy from UC Berkeley. The novelty alone could have gotten you into a great Grad school and you could have had a lucrative academic career. You didn't
During the height of your career you had the opportunity to write your ass off and have tons of books that would have been out there for decades now. You wrote one.
You started your own religion for crying out loud! Who can't make money starting a religion?*
I bring this up not to pick on Isaac, but to illustrate the opportunities that people DO have to make money doing what they love. They just need to work. Hard. If you do not want work your ass off to take advantage of opportunities to make money doing what you love, or just desire more job security, than get a day job. If the issue is that you just don't want to work than I have no sympathy. No one is going to pay you for being an "Elder", which basically amounts to dude that has been around a while that might deign to answer a few questions if you corner him at a Pagan festival.
Jow makes an excellent point in that you can either be paid as a Priest or a Tradesman. Possibly both.
If you want to be paid as a priest, you have two choices. Become clergy in a religion that has paid clergy already OR start one. Figure out your take on spirituality, write a liturgy, start a church, spread the word and either pass the hat or charge at the door. Usually a bit of both.
Most Christian Churches pass the hat. They can afford to do so. "How can they afford it you ask? Volume!"
Besides, there is that whole "Simony" thing.
In Buddhist circles there is a combination of the two. Centers get supported by donations like a church and traveling Lamas offer specific teachings that will draw in a lot of out of towers for specific "requested donations".
If you are a tradesman than you charge for your craft like I do. Specific teachings and or services for specific fees.
Vodou is an interesting combination of both, and a model that I always though would work well for Witches. Take donations or Dues from the Coven, but charge for your WitchCRAFT when working for the general public.
There are of course various taboos that people have on charging for magic. Strangely the same people that do not want to be charged for magic have no problem charging for readings or reiki sessions. I guess those don't count. It's a shame because sometimes a reading reveals a problem that could be avoided by magic, but if you are against paying or charging for spell work you probably are not going to receive or offer that help.
I occasionally get interviewed by someone that is amazed that I do magic for money. They treat it like it is a real novelty or going against tradition. Most Neopagans and Mages are sheltered from the way that magic operates in the rest of the world. The reality is that outside of very modern western neo-paganism and ceremonial magic, charging for magic is the norm.
*If I ever start a religion, I promise you that I won't be all L Ron Hubbard about it, but I will also make damn sure that it sustains me financially in some way.
