Final answer:
The phrase 'time is money' is a metaphor that highlights the importance of using time efficiently, equating wasted time to financial loss, particularly in societies where productivity and economic gain are highly valued.
Step-by-step explanation:
The phrase 'time is money' is a metaphorical expression suggesting that time is a valuable commodity, and thus it’s important to use it as efficiently as possible. This notion reference the idea that every moment wasted could be spent on actions that can bring economic gain or be productive in other ways. Much like money, time is a resource that is limited; we only have 24 hours in a day and must choose how to best allocate it. In capitalist societies where every action is measured against its financial value or productivity, this comparison becomes especially significant. The expression implies a worldview where time not invested wisely is tantamount to financial loss.
