So it's not about the end-user or the community, it's about the "indie comic creators" lining their pockets?
I don't know how you come to the conclusion that anybody working for 6 months on a project and making 5k is lining their pockets. Quite the opposite I'd say.
Clint Stoker's profit margin does however align with the 'back of an envelope' estimate I did a while back on the cost of producing a book.
If you take Clint’s campaign as a reasonable benchmark for comicsgate success, then you're talking about 1k backers (which is a conveniently round number).
I reckon that your average 48 page CG book probably costs around $300 per page if you hire a competent artist, colourist and letterer. (200 per page to the artist and 100 to colour and letter)
That's $14,400 just to complete the book. That is a cost you can reduce to nothing if you do all that yourself of course, but what's the time that takes worth to you in monetary terms? It's still probably 3 months of solid yet unprofitable work for a creator.
I looked at Print Nina's site for a quote, (the number of MAGA! boys that choose to print in commie China is amusing to me) and I reckon you're talking about $3 per unit to print 1k books at that economy of scale.
So you're looking at $17,400 jsut to get the book into your hand before you even fulfil the campaign.
I'd guesstimate that you're looking at about $8 to deliver an order (within the U.S.) when you count the cost of a gemini mailer and postage, or about 8k.
So, with a thousand backers, you're looking at $25,400 to fulfil a campaign (and that's doing it yourself, which should be feasible with a thousand backers) and without adding a multitude of stretch goal 'chachkies' as Zack calls them.
By my estimation, anybody that launches a book that makes 25k or less is not going to see much if any profit for all that work. I think EVS said as much once and it caused a minor kerfuffle in the community because people didn't want to hear that most of the books in CG will always remain labours of love rather than a career, unless your campaign is doing somewhere in the region of 35k, creating a book is an utter waste of your time IMO.
You'd need to do that 3 or 4 times a year just to make a basic bitch living at comics and anybody who's campaign is doing 5-15k is taking a bath on it every time they publish.
None of that is denying that the price point is an issue, it is, and going forward I think many creators are going to need to find ways to reduce costs but nobody (apart from a select few) is making a ton of money on their books.
