Imagine you were the ruler of a kingdom which had a magical machine that made beautiful objects, but the machine could only be operated by a select few who knew the correct magic spells.
The only problem was the magicians who operated the machine, although they worked very hard, wanted to be paid lots of money. This rankled a bit, but you paid up as otherwise you could not get your beautiful objects.
One day a charming, suave visitor from another kingdom offered you a deal. He would look after your magic machine for you and would pay the greedy magicians for you, but he would charge you less than what you paid them currently (because he had a magic wand called ‘The Economy of Scale’).
You know a good deal when you see one so you bite his hand off. Happy days!
Not long afterwards you decided you wanted some different beautiful objects, because you were a bit fed up with the beautiful objects you already had, and government legislation had decreed that the old objects were not up to health and safety standards.
“Oh dearie, dearie me” says the manager from the other kingdom (the charming suave visitor had not been seen since you signed the contract) “it will be costing us a lot of money to be doing these changes. We will have to be passing these costs onto you I am afraid.” “Oh” you sigh, “it never used to cost that much, I wonder what happened to The Economy of the Scale? Still I suppose we have to have them done, and they need to be ready by Tuesday.”
“Goodness gracious me” says the manager from the other kingdom, “we cannot be making changes that fast. They will be ready in October next year.” “But” you protest “If I have to wait that long, my country will be bankrupt. My old magicians used to be able to make changes in no time.” “Ah yes” says the manager from the other kingdom, “but half of them have left since we don’t give them pay rises anymore, and the other half have to work for three other kingdoms as well as yours, or else we would be unable to make a profit out of them.”
On the way to the bank to ask for a mortgage you see a sign “Free lunch for kings” You are hungry, but you walk on.
