I completely agree with what you said here and that is understandable. I completely understand missing the odds and having the by product animals. What I find overly irritating is someone just breaking in and buying 3 pastel males and a bunch of normals and just breeding to breed. That is pure irresponsibility and not just from a standpoint for the industry but for the animals themselves.
A great example of this is a guy I know who opened a pet shop and wanted to stand out. So he purchased a bunch of WC adult females and pastel males and attempted to breed. He got a bunch of normals and pastels and then could not sell a single one because of the market prices and what he had them marked at. So he then discounted them and lied to people about the genetics and so on and so on and then ended up creating a lot of people who purchased the animals who were breeding them and creating the same thing over again when they tried to sell them. It is a downward spiral after that. Luckily he is now out of business but he did create a bunch of people who had high hopes of making money and ended up with nothing in the end. Should they have done their research? Yes. But not everyone will.
