Debt inevitably incurs costs: the interest and the usage fee. Borrowing means using someone else’s property as if it were my own. When the purpose of borrowing is achieved, or when the agreed time to return it arrives, it is returned to another person’s possession, and the borrowing cost is no longer incurred. Costs also serve as the basis for production and are the consideration for almost all debts, regardless of the borrowing purpose. The frightening aspect of debt is that it incurs costs and requires repayment of the principal. Originally, the principal was not mine. Thus, spending with other people’s money exposes you to significant risks, especially when you spend on perishable consumption that disappears after use. If you spend someone else’s money without differentiating between production costs and costs for extinction, you are on the fastest path to destruction. Therefore, luxury can ruin even the rich. - 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”
