Even with Wagyu and Kobe, the whole cow isn't getting turned into premium cuts of meat. Burger and sausage are going to be a byproduct of the parts that aren't high margin proportional to the demand for the rest of it. Kind of like how eggs are so cheap because they are a natural byproduct of the chicken meat industry and the insatiable American lust for all white meat breast. I wouldn't be surprised to see an effective advertising campaign to make burger et al more "premium" as plant based substitutes take off and the price go up as a result of that. Kind of how Angus cows got to be big in the first place.
