I've seen some of the more expensive snakes being mistreated, so the price of the snake doesn't garrantee that a snake will be treated right although you will probably be less likely to find a 10K snake being mistreated.
Personally I like most normals, and slight variations of normals better then a morph, so that's what we buy.
The reason you see morphs going for so much more then a normal is that the morph is rare.
It's like a coin, a double stamped coin doesn't look any better then a regular coin but it's worth a heck of alot more to a collector then a normal coin.
People collect things for different reasons, who cares why they collect as long as they take care of their collection properly.
