FWIW I live on the coast in a place where people eat a decent amount of seafood (anecdotally), and fish is also one of the most expensive protein options. Significantly more expensive than chicken/pork and often even beef. Up until I got my first post-college dev job, my family could not afford fresh fish and thus didn't eat it. Now I live comfortably and can afford it, but it costs as much as a nice piece of beef (like a ribeye), and since I didn't eat fish growing up, I'm going for that ribeye 9 times out of 10.
