Solomon draws up an account no bank ever would: he calculates the "real value" of dirty money versus the "vital profit" of righteousness.
The Inflation of Sin
It seems like an exaggeration to say dishonest money "has no lasting value." After all, it buys cars and houses. But Solomon is looking at the end. Money earned through lying, fraud, or exploitation carries a "virus." It doesn't bring peace, doesn't buy health in a moment of anguish, and has no value in God's Court. It's like Monopoly money: it looks real during the game, but it's worth nothing in real life.
Righteousness as a Shield
Here, "righteousness" (Tsedakah) isn't just the judicial system, it's moral integrity, charity, and honesty. Being righteous is life insurance.
Physically: whoever is honest doesn't fear the police, doesn't get involved with dangerous people, and avoids the stress of lying (which kills).
Spiritually: righteousness (which comes through faith and is shown in works) connects us to Eternal Life.
The Long Run
The shortcut (dishonesty) promises quick gain but delivers death. The right path (righteousness) promises hard work but delivers life.
