Normals are prevalent and inexpensive. We live in a society that, unfortunately, has a "disposable pet" attitude towards most animals. These are the people who readily buy (or convince a parent to buy) the cute and inexpensive normal baby they saw at a pet store or a reptile show and the same people that decide a few weeks, months, or years later that they don't have the time for the animal and want to get rid of it.
High quality morphs are certainly cute but not inexpensive and not likely to be the impulse buy that turns into a neglected animal advertised on CL. People who invest the money into quality morphs are usually invested in its care and long term well-being.
You find poorly cared for animals on sites like Craigslist and Kijiji all the time and this wouldn't be the case if more people put forth some effort in educating themselves about the basic care needed for the animal(s) in question. A little self control wouldn't hurt either. People need to stop feeling cash burning in their pockets as soon as they spot a nice looking animal for sale.
