The rich man is wise in his own conceit (comp. Proverbs 18:11). A rich man thinks so highly of his position, is so flattered by parasites, and deems himself placed so immeasurably above social inferiors, that he learns to consider himself possessed of other qualifications, even mental and intellectual gifts, with which wealth has no concern.
This purse-proud arrogance which looks upon financial skill and sharpness in bargaining as true wisdom, is confined to no age or country. But the poor man that hath understanding searcheth him out (Proverbs 18:17).
Wisdom is not to be bought with money. A poor man may be wise, his poverty probably making him a keener critic; and if he is brought into communication with this self-deluding plutocrat, he soon sees through him and recognizes his real value.
Septuagint, "An intelligent poor man will condemn him."
