Jack is a sheep farmer. He gets some government subsidies,and also works long hours to keep his sheep happy and healthy. When his beastsare ready for slaughter, he offers them to an abattoir. The abattoir is verychoosy and may reject Jack’s sheep, which is a disaster for him, as there is noother route to the market. If he is lucky the abattoir will accept the animals,slaughter them and sell them, at a large profit, to the supermarket. Jack doesnot see any of this money. The populace struggle to afford the price of meat,but the government has no control over this. When Jack feels like a nice pieceof lamb, he buys it from the supermarket. Meanwhile, Jack provides his servicesfor free as an inspector of other farmers’ animals.
