I think that you have an interesting point here. However, prices are in the hands of the seller AND the buyer. Why did the super high price morph drop in the first place? Was it super saturated in supply? Was there a "defect" found? Was the price lowered to move along the snake more quickly? Was the priced lowered to compete with other people lowering their prices? Depending on the price drop, I'm sure there can still be money to be made as long as quality babies are produced. Mike Wilbanks has a good video up on Youtube called "The Ball Game" and it has a part 2 as well.
In econ, everyone is happy when the price hits equilibrium (the point of which supply meets demand at the perfect price point). I think that as long as people are willing to pay some amount of cash on a morph, the morph could stay at that price point. It is inevitable that prices for all morphs will fall, but I do all morphs will hit a plateau and stay there. I think that single genes will always be less expensive than a double gene (not saying that a bumblebee is worth more than a GHI).
To answer your question, I do not see myself as a large scale breeder. I see myself as a small scale breeder that is hopefully going to produce higher quality/ more sought after morphs (and morphs I like).
