Survival of the Fittest and Cooperation: Examining the world from the perspective of competition for survival reveals that only the strong and fittest survive, a concept often referred to as “Falling Prey to the Strong and Survival of the Fittest.” However, there are cases where this principle does not apply, when each entity cooperates with the others. Then, rather than surviving because they are strong and adaptable, it may be that they are strong and adaptable because they survived. Cooperation is an act of a very peculiar nature. The truth is, those who cooperate are the strongest. - Joseph’s “just my thoughts”
Even though a country's total population is decreasing, the economic situation could be improved by increasing the total economic activity of the remaining population after the decrease. Of course, there is a statistical population threshold below which this effect occurs. Nevertheless, this effect would not work in the case of a force majeure, such as a natural disaster or the outbreak of war, however, this assumption would be valid because a rapid population decline is a highly exceptional event that would not normally occur. Therefore, an increase in the economic activity of this population should be required during an economic recession. Applying this perspective, for building a solid relationship with your followers on Instagram, the number of followers is less important than the activity between them and you. This is called the "Engagement Rate (ER)". - Joseph’s “just my thoughts”
