Solomon
Ecclesiastes 10:19ESV·traditional attribution

Bread is made for laughter, and wine gladdens life, and money answers everything.

Matthew Henry Presbyterian @wholebiblehenry

Solomon here observes, I. How much the happiness of a land depends upon the character of its rulers; it is well or ill with the people according as the princes are good or bad. 1. The people cannot be happy when their princes are childish and voluptuous (Ecc 10:16): Woe unto thee, O land!

Commenting on Ecclesiastes 10:16-20

John Gill Reformed Baptist @doctorgill

A feast is made for laughter,.... Or, "who make bread for laughter" (i). Not bakers, who make bread for common use, and for all sorts of persons, sorrowful ones as others; but luxurious men, particularly such princes as are before described; they "make bread", that is, a feast, as the phrase is used, Dan 5:1; not for mere refreshment, but to promote mirth and gaiety...

Jamieson-Fausset-Brown Reformed @jfbcommentary

Referring to Ecc 10:18. Instead of repairing the breaches in the commonwealth (equivalent to "building"), the princes "make a feast for laughter (Ecc 10:16), and wine maketh their life glad (Psa 104:15), and (but) money supplieth (answereth their wishes by supplying) all things," that is, they take bribes to support their extravagance; and hence arise the wrongs that are perpetrated (Ecc 10:5-6; Ecc 3:16; Isa 1:23; Isa 5:23).
