Heh, I get the joke.
But really, is it really the problem? I'm considering the idea from both angles of supply and demand right now. I mean, once upon a time ago, stuff like crab and lobster was considered poor persons food. It was so plentiful that the story goes 'You could just walk down to the local ocean side and scoop some out of the ocean without any trouble'.
The way I see it is this. Pricing is indicative of supply and demand. If demand is high enough, suppliers will attempt to meet that demand. When demand wanes, supply burgeons, thus creating a reason to lower prices so that demand matches supply again. So in a sense, while price would seem to be the culprit, I think it more or less comes down to the fickle nature of the human.
Take red lobster for example. I never eat there, because they always somehow have some 'sale' happening. This means one of two things for me. Either they are selling old product as "fresh" which is not possible in many places they operate, or they are selling under the 'actual' price to increase demand to help meet supply.
Now extend that to the rest of the industry. Where does that land us?
In my mind, it means we are over fishing the species, all because other companies like RL allow for it to happen by continuously artificially spiking demand. Because at the end of the day, even if RL doesn't make profit, the fishermen do. RL and others like them keep buying it. It doesn't matter to the supplier of these restaurants if the food is being eaten or tossed. It's already caught.
Make sense?
