Wouldn't there be a movement for a blood entitlement, and how would demographic factors shape that program?

I can't NOT link to a blog post titled "More Vampire Economics, Please." I know I have nothing to say about it other than shrieking with delight about the very existence of said blog post, but I don't really care. Here's my favorite section:

The most interesting thing, though, is that there’s a news scroll at the bottom of the screen, and as the debate is wrapping up, a headline noting the blood shortage scrolls by, followed by the line, “Vampire economists say…”

And then it cuts away.

This happened at the beginning of the film. And it drove me COMPLETELY. NUTS. for the following 90 minutes. What do vampire economists think about the blood crisis? I really want to know! Is there a vampire central blood bank? Are there interest rates? Does it get used as currency? Maybe they went off the blood standard at some point?

Okay, that’s probably getting a little too nerdy. But the implication is that there’s this whole social structure organized around blood allocation. Yet all we see is a single company that stupidly burns through its resources without any interest in, say, setting up more efficient, long-term sustainable blood farms; surely a ripe human should be able to pump blood into the system for 60 or 70 years.
