It doesn't really have anything to do with what I like. That kind of cattle wouldn't work for me, and it's not what you find in most commercial operations around here. I'm sure those bulls suit operations in the desert southwest just fine.
I take exception to Mr. Pharo generalizing on couple of items. First is input costs, input costs vary over time and location; right now the largest(biggest risk) input cost throughout the cattle supply chain is labor. It adds a lot of cost to the final product at a store or in a freezer. You can't square Mr. Pharo's pounds per acre logic, with the fundamental truth that there is less labor cost per pound of beef in a larger steer. The second point that gets glossed over by zero input people; order buyers are not stupid, they know what they are buying and from whom. There are pretty big discrepancies in $/cwt is every weight class; sometimes 20-30%. You might be cutting your inputs but are you getting average price, or better?
Naturally, everything I just said could be thrown back in reverse for people that chase absolute pounds of weaning weight, and it would be correct. Efficiency lies in the middle.
