Where I live, the average farm loses money every year. The only reason farming exists in its current form in this area is because of government subsidies. There are big lobbying groups to make sure that specific methods are paid for by taxes, even if they aren't efficient. Also, the average age of farmers is over 60, so they are extremely unlikely to try innovative methods. Only once the current generation dies off will there be any major changes, because right now everything is prescribed and paid for.
