How do some people make money through injustice today? Some make money by paying unjust salaries to their workers. Some make money by getting a percentage in government projects.
It is better to gain little money by doing right, than gaining much money through lying, cheating, and stealing. Neither prosperity nor poverty is good by itself. What makes it better is the fear of the Lord in it, as manifested in one’s personal integrity.
Thus, the better life is not prosperity through corruption, but little money through personal integrity.
