Labour is creating wealth
All wealth is created by labor.
It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own self-interest. We address ourselves not to their humanity but to their self-love, and never talk to them of our own necessities, but of their advantages.
To widen the market and to narrow the competition, is always the interest of the dealers…The proposal of any new law or regulation of commerce which comes from this order, ought always to be listened to with great precaution, and ought never to be adopted till after having been long and carefully examined, not only with the most scrupulous, but with the most suspicious attention. It comes from an order of men, whose interest is never exactly the same with that of the public, who have generally an interest to deceive and even oppress the public, and who accordingly have, upon many occasions, both deceived and oppressed it.
The opportunity cost (or alternative cost) is an economic concept that considers the cost of not doing an activity so that to use its resources to achieve another one.
These costs are not counted as such but are taken into account in the decision-making process.
The opportunity cost translates as the company's decision to allocate one available resource to one project rather than another in order to make the best possible gain. In in the example above, if the company decides to assign its production tool to the X model to the detriment of the Y model, and retains the B2 option for some strategic reason, the cost of opportunity is (72-55) € 17 million.
