When we exchange what we need, we use money as a medium instead of trading ‘goods for goods.’ In this context, money acts as a means of exchange. When we exchange what we need, we also build wealth by passing on added value to each other. In other words, money functions as both a medium of exchange and a measure of value, as well as a tool for accumulating wealth. But isn’t this a bit strange? Although exchange value comes from goods and surplus is generated from this exchange value, the object used to measure and accumulate wealth is money, not goods. This is because money alone has the privilege called ‘compulsory circulation power.’ In other words, even if value is created, added value cannot be realized unless it’s exchanged. The ability to enable such exchanges is what we call ‘compulsory circulation power.’ - Joseph’s “just my thoughts”
If capability defines whether you can do something, ability determines how far and how much you can exercise it. Capability is a possible state with a purpose, while ability is a state in which a specific objective is set for achievement. Therefore, without a goal, there is no actual ability. People with such excellent abilities are known as specialists. The result of ability is termed performance, which reflects how well the goal was achieved using that ability. - Joseph’s “just my thoughts”
