The message that King Solomon, wisest of all men who ever walked the face of the earth, is conveying is to live within your means, don't owe money to anyone and you'll sleep like a baby at night, even if the only thing you have for dinner is a glass of water and a dry piece of bread. On the other hand, those who live lavishly and throw the "Goodbye Columbus" and "Keeping up with the Goldbergs" weddings, drive fancy cars and live in fancy houses - yet they owe thousands (tens of, hundreds of, or more...) of dollars to everyone in town - don't have an ounce of inner peace. In the middle of their rib-steak dinners, creditors are phoning and texting nonstop. That's what King Solomon calls the "steaks of strife". Who needs that?
Hashem gives us everything we need to live within our means. When a person can't make ends meet, he or she should assess themselves as to whether they're spending money needlessly, buying things they don't need or just trying to keep up with the Jones's (or the Goldbergs). My esteemed and beloved teacher and spiritual guide Rav Shalom Arush says that thinking that Hashem will cover debts accumulated from living above one's means if false trust. The true manifestation of emuna is when we're pleased with our lot in life; that means living within our means.
