Beef is a case where there are some very obvious things(texture, fattyness, chewyness etc) that make eye fillet a much more pleasant eating experience than other cuts of meat and there's a lot less of it per animal. If you can pull that off you can make the general case of decent meat much more affordable.

Of course, there'll always be Wagyu and Kobe, but that's a much smaller market than just the high end of normal meat.
