This proverb means that those who consume too much or waste resources leave nothing behind for others or for themselves in the future. In an economic context, it can be used to criticize prodigality, which leads to poverty. For example, someone who spends without thinking might not leave anything for others or even for themselves during tougher times. The equivalent English proverb would be « Living like a grasshopper ». It highlights the importance of moderation and careful management of resources.
