Saskatchewan farmers have done very well since ~2000 or so. The 80's and 90's were very rough.

Yes, costs have skyrocketed -- combine harvesters start at about a million now. But wheat prices and yields have been high enough to more than compensate.

But Saskatchewan farmers are a great example of a low cost producer. A Saskatchewan farm usually runs about 10,000 acres per operator. UK farms with a couple hundred acres can't compete.
