Growth why focusing on growth?

Nowadays, in our society, growth represents the main focus. For example a country aims to reach a growing level of gross national product (GDP), a company tries to increase profit, a man or a woman wants to grow his or her wealth.

Let's define an entity a country or a company or a woman or a man. Every entity want growth. Why?
First, let's define growth? Growth can be characterised by something which increases. It can be triggered consciously or unconsciously.

We will try to understand how the concept of growth has developed over time. As we have already done in other analysis (see Communication - Humankind beginning discussion), we will proceed to a simulation with assumptions. Suppose during the prehistoric period, a human is trying to survive, which constitutes his primary objective. To survive, the human needs food such as nuts and fruits for example. When he finds a nice tree with plenty of fruits, he will eat some to appease his hunger and probably keep some for later. How will he store the surplus of food? Let's assume he is digging a hole where he can bury the food, then he can come back and eat later. It means the human has to stay around to avoid long walk to get his food when he is hungry. If he finds another tree nearby with fruits, the possibility of coming back easily to his hidden place allows him to store more food and to contemplate the growth of his treasure.
If we step back a little bit, the first feeling of growth comes from a certain abundance of food greater than what it is needed to appease hunger at that specific moment, allowing at the same time the human to save food for the future.
From this point, the human objective will be focusing on increasing his savings in order to survive in this harsh environment. It means the human has a sense of future scarcity and savings will help to mitigate this risk of scarcity.
If the human was living in an environment where food was available at all time, then he will not need to save for the future and to contemplate the growth of his saving.

Therefore the first concept of growth is linked to the environment where food scarcity pushes the human to save for the future. On the other hand, if food was abundant, the human would not need to save.

Moving on the time spectrum to our current society, growth has become the main driver how the different entities interact. In the prehistoric time, food represented the main good the entity was focusing on to grow. Today, food has been replaced by money. Every entity are trying to increase their amount of money in order to be able to buy any goods.

The main issue resides in an environment with limited resources. Each entity thinks of growing their wealth for the future.
If we come back to our simulation in the prehistory, when the human found these trees with more food than needed, he has been made aware of several concepts unconsciously and simultaneously. We mentioned the concept of growth, we can now say the human has developed the idea of saving and also the thought of the future. Growths, saving and future have become gradually part of the human life, mostly unconsciously, then progressively with more and more conscious of these new concepts.
