Let's take a look at the question again, but replacing
psychic abilities with another God-given talent, painting... (sorry couldn't get the bold to disappear after the cut and paste):
It seems that a lot of people wanting paintings are at a point when they really need beauty in their lives. We don’t all have this gift and indeed can not ‘grow’ this gift. It is the most sacred gift one can have. Wouldn’t it be more in line with a life purpose to grant this gift free, and make your money from ads and donations on your site like your husband does? I’m not saying you don’t deserve to make money from your gift at all. I am saying that your gift is God given and would be lovely to be enjoyed and used by as many people as possible.
While there's certainly often a belief that artists can't earn much money, we certainly don't expect them to give away their talent for free
Erin provides value and is a professional. Her prices may seem steep to some, but they are not at that level because of greed - rather the complete opposite... For example, setting a price to manage supply and demand allows Erin to manage her time and hence give her full energy and attention to those for whom she reads. She is not distracted by the need to find alternative income sources, nor is she distracted by "non-serious" clients who want a freebie to test her abilities, or for fun, or because they have to run every decision by a psychic before they can act. Instead, Erin's prices ensure a meeting between a quality psychic and a serious client - that synergy results in a good outcome for all.
Sure, there are cheaper psychics out there. Some may even be as good or even better than Erin. But, as Erin pointed out, she is very open on her blog about her process and her abilities. I would rather invest money in getting a reading with someone I trust rather than potentially waste $60 and be disappointed (and then have to spend another $60 with someone else and another $60 with someone else...).
