The economies of scale in industrial farming are jaw-dropping. Raising birds on a small family farm is vastly more effort, and is much less optimized for turning the cheapest possible feed into meat.
Go to your local farmer's market and you'll find similar prices: $8-12 per pound.
That bird will also taste much, much better. For starters, it's not "injected with a solution of salt, sugar, and turkey broth", as your grocery store turkeys are. That's why turkey meat is so dry and flavorless. For another, it got more exercise (which is why the dark meat has more flavor than white) and ate more than just corn.
It may not taste ten times as good; there really isn't a good metric for that. To my mind, it's more important that the industrial conditions that allowed that cheap bird to be so cheap are pretty horrifying, and I don't like participating in that.
