It's getting to be like writing novels. Lots of people do it. The barriers to entry are low. But few can make a living at it.
I don't think few people make a living at writing novels because of competition; if more people wrote better novels I imagine novel sales would be much higher.
People are writing good novels faster than I can read them. Perhaps there's some great, untapped supply of people out there who aren't finding enough that's worth reading, but I'm certainly not in that camp nor is anyone else I know who reads regularly.
You say you read regularly, so I'm thinking you would read books many wouldn't take the time to read. I'm talking about writers which have such interesting stories that they bring in less avid readers -- the way Harry Potter did. This is actually a subject I have a lot of interest in. Can you list the last few books you've read?
Last few novels I've read, in reverse chronological order:
- Past Imperative, Present Tense, and Future Imperfect by Dave Duncan. (Trilogy.)
- Foreigner, Invader, Inheritor, by C.J. Cherryh. (First three books of an ongoing series; rereads.)
- Babylon Babies, by Maurice Dantec. This doesn't really count, since I gave up halfway through--the translation is horrible.
I'm currently reading Vellum, by Hal Duncan.
I have, I think, about 5-6 more books on my to-read pile at the moment, and I could triple that with a visit to the bookstore. (I'm avoiding visiting the bookstore because my budget would not appreciate the experience.)
As you can see, I mostly read SF. This list is a bit unusual, in that it includes a number of books from the same series; I usually mix things up more than this.
It's true that I read books that many wouldn't take the time to read. I don't think that's because those books are less interesting; I think it's because most people have much less interest in reading than I do, and therefore are satisfied with fewer books.
It seems to me that you're formulating an argument where I have lower standards than people who read less--that people who read few books stick to the cream of the crop, while people like myself who read more are willing to read inferior works as well. As a counterargument, I submit Dan Brown, an author who produces (from my perspective) works of such execrable quality that only a person with little awareness of how good books can be would waste their time on him.
To shift arenas: Consider two people. One of them eats nothing but steak and potatoes. The other is Anthony Bourdain, the host of the Travel channel's "No Reservations". Would it be correct to say that the reason the former eats such a smaller variety of food is that there's a lack of truly good food that lives up to the standards of the almighty steak and potatoes?
Of course not. We'd say that Mr. Steak & Potatoes just doesn't like food as much as Bourdain. (In general; he likes his steak just fine, and there's nothing wrong with that.)
Or to take myself as an example: I don't watch much television. Is the problem that there's just a lack of really good television out there, and I'd watch more if someone started producing more good shows like The Wire? Well, no. The problem is that I just don't like television all that much, and would rather spend my leisure time on other activities like books, video games, and programming. There are already plenty of TV shows that I'm certain I'd enjoy...if I had time to watch them.
So, no, I don't think that people in general would read more if only there were more good novels being written. There are plenty of good novels out there.
It's true that I read books that many wouldn't take the time to read. I don't think that's because those books are less interesting; I think it's because most people have much less interest in reading than I do, and therefore are satisfied with fewer books.
I totally agree with that. A point of clarification for what I meant in terms of "interesting" is in order. I agree that any of those titles you listed are very likely highly interesting, but exactly what is "interesting" is subjective. In no way did I mean to suggest books you enjoy to be inferior. Let me provide a supporting example of my own. I doubt many people would consider Beethoven's 5th symphony inferior music, yet no one would consider it to make Billboard Music's top 20 list anytime soon, or more youths than you can count on one hand blasting it from their cars. In this way you can see what I mean is not inferiority, but rather a broader appeal to the overall market. To put it another way, operas make plenty of money, I'm sure, but I doubt their revenues compare with even low grossing movies. Would I like more people to be into reading, or operas? Yes, but that's not how things are. To appeal to a larger audience, any work of art (especially a novel) would do well to be more than just good; it needs to be really great, so that even those with a passing interest in the medium will take the time to enjoy it.
I don't think few people make a living at writing novels because of competition; if more people wrote better novels I imagine novel sales would be much higher.
