What is the meaning of this sentence?

"Wealth gained hastily will dwindle, but whoever gathers little by little will increase it."

 

-Noticeably, the phrase means that money obtained through dishonest means goes away or waste away whereas money acquired through fair means by way of hard work, diligence, labor, etc. will ultimately increase one's initial wealth or richness.

Step-by-step explanation

The above statement simply implies that money acquired through fraud or any other injustice/illegal means in order to make someone in particular become rich quickly will be diminished eventually. On the other hand, if any person obtains money through fair means such as working hard on daily basis, increase his/her overall wealth. Most predominantly, the phrase logically condemns the acquisition of wealth through dishonest money like obtaining wealth through corruption, money laundering activities, robbery, drug cartels, fraud activities, etc. It upholds wealth procurement through just means like by way of labor and diligence because such means will sooner or later increase the initial wealth.
