Final answer:
The term concerned only with money refers to an obsessive focus on financial gain, disregarding other aspects of value. Money's main function is to serve as a medium for trade, with liquidity being a key characteristic that describes how easily it can be converted into goods or services.
Step-by-step explanation:
The term concerned only with money implies a focus on financial gain or wealth accumulation without regard for other values or considerations. In the context provided, it seems that money is seen not as an end itself, but as a means to trade for goods and services. Money's potency lies in its wide acceptance as a medium of exchange, a unit of account, and a store of value that simplifies trade and economic activity. Yet, the quest for money for its own sake neglects its ultimate purpose in facilitating real-world transactions.
Liquidity of money is an important aspect in economics, referring to how quickly it can be converted into goods or services. Cash, for instance, is highly liquid, and easily used for purchases, unlike money in savings accounts, which may require additional steps like going to a bank or ATM. The liquidity of different forms of money, such as checks or credit cards, affects how they are utilized in economic transactions.
