In the Twentieth Century they had a theory about Hydraulic Modelling of economics. Academic economists believed that money flowed through an economy like water through plumbing, So they could represent trade with physical pipework.
In the new Millennium we experts in economics have moved forward. At least we have where I live. The pipework model only theoretically represented the economy. We then realised that we could cut the physical model out altogether, and model from pure theory. This brilliant insight set us free to plan our economy according to axioms grounded in pure faith.
We are now managing our economy by our original and unique Vacuum Theory of economics. Everybody knows that nature abhors a vacuum. So it is obvious and does not need proving, that if you drain money out of an economy more must be automatically sucked in to replace it. Our other axiom is that growth is sustainable and Malthus's two hundred year old twaddle about exhausting resources is thinking that has long passed its use-by date. So it is perfectly possible to suck in more than you are draining out.
We have been busily implementing this by creating as many drains on the local economy as we possibly can. We have not only encouraged overseas businesses to take over our commerce, but also abolished all tax on the profits they repatriate, so maximising the loss to our local economy. Our piece de resistance will be the new world class incinerator. We are lavishing perhaps four or five times the cost of modern alternatives on the plant itself. We will also be bringing in civil engineers for massive surrounding works to make the location suitable, costing at least as much again. All told we can hope to dump almost 300 million pounds from the economy. By our theory, the inrush of replacement money and the inevitable growth will give us back half a billion.
Unfortunately, my advisers have not yet explained to me exactly how the money will suck back into our economy. However, as an act of faith, already we have been busily implementing our vacuum economics, and I am sure that it will soon become clear just how well they work in practice.
