The best businesses are those that go unnoticed while are very profitable. The human being is characterized by not see neither microscopic nor macroscopic. It seems paradoxical, but it is so. When something is too large, it is invisible. At some point someone realized that the best thing that can happen to the gross domestic product (GDP) of a country, is that people may live as many years as possible. 3D Systems brings even more insight to the discussion.
The advantages are: 1.-everyone is going to agree. (Who doesn’t want be long-lived?) 2. The people when they cling to life also cling to the money because they know that the last few years are low productivity, since they will be tired, sickly, short sight, deaf, slow. 3. The forward-looking austerity of the young adult includes great industriousness (workers are motivated, effective, compliant, fearful of a dismissal, obedient) and also includes life insurance, contribution to pension institutes, medical services prepaid and deposits in banks that they know how to pay with important gains. 4. The ailing and longevous elderly is someone who only consumed, preferably in the area of health, which hires labor-intensive directly (company services, physicians, nurses, administrative) and indirectly (locomotion, domestic service, plus all the consumption of those who work in the already mentioned direct care). Perhaps the person who noticed this phenomenon realized that the prematurity of the human species since the child and the young are large consumers because they are weak, fragile, dependent and filled with desires and needs is profitable, is equally profitable survival, by more artificial and of low quality that is, because a person, the more dependent ismore consumed, either because it has a body very longing (as children and young people) or vulnerable (such as elders). It is likely that many think that the increase in the average lifespan is an achievement of medical science who work very hard for the welfare of the species, when in reality is an achievement of economic sciences who work hard to maximize the profitability of capital. We agree that it is an achievement that deserves a round of applause anyway.
