The sting here isn't that greed is bad—everyone knows that. Solomon is making something harder to swallow: he's arguing that the *structure* of wanting wealth guarantees unhappiness, not because you fail to get enough, but because the appetite itself is insatiable by design. A person earning fifty thousand dollars might feel genuinely poor compared to someone earning five hundred thousand; bump them both up tenfold and the gap persists, the dissatisfaction unchanged. What makes this observation matter is that it suggests no amount of financial success will deliver the contentment people actually crave—you can't solve an emotional or spiritual problem with a mathematical solution.
