When I was a child, you could buy baby turtles for less than a dollar and baby caimans for less than $5 at the local dime store. They were considered novelty items - disposable pets. Parents would buy one for their child until they grew tired of it, then try to give it away, flush it down the toilet, or "kindly" turn it loose in an alien environment. In recent years, I have seen the same thing happen with cheap, wild-caught lizards of various types. I don't think that kind of "cheapness" is good for the animals, or even for the attitude of people buying them. It is sad, but true, that people tend to value what they pay for, and value it more if they pay more for it.
On another note, there will always be people who breed corns as a "labor of love", and I expect to always keep some too, no matter what the price, because I really like them. But if they become too cheap, I won't be able to afford to keep many, and won't be able to afford to do all of the projects that I do now. Very few herpers are rich, so that will apply to most of us. Cheap prices means that it becomes a very part-time hobby for most everyone, and that offerings become more of a hodge-podge of "what you see is what you get", instead of known bloodlines available for people who really want to work with something particular. I am not complaining, because I believe in the free marketplace, and that you have to just deal with whatever it produces. But sometimes the effects are more (or less) beneficial to a particular activity, and you have to adjust your actions accordingly.
In conclusion, I think it is great that corns are affordable (compared to ball python morphs, for example), but if they become disposable pets, I don't think it is good for anyone. All of this is just my own opinon, others may feel differently.
