I’m not all so sure about there being less need for milk. There is some lactose intolerance, yes, the main problem is oversupply. There is way more milk coming on than there is market, and the Mega operators are busy building more bigger dairies. Fly over the Texas panhandle at night and look down at the glowing milk barns. It looks like a city down where it ought to be dark fields.
You wont find any of that fake milk in my house. Milk is milk, it comes from cows, not soybeans.
But why overproduce if the need isn’t there? Supply and demand would tell you to limit production until it gets back in line with demand.
