Human prosperity never rests but always craves more, till blown up with pride it totters and falls. From the opulent mansions pointed at by all passers-by none warns it away, none cries, "Let no more riches enter!"

The lines express a central tragic idea in Aeschylean drama: prosperity tends to breed further desire, and unchecked accumulation swells into hubris (overweening pride) that invites collapse. The image of “opulent mansions” admired by passers-by underscores how social praise can reinforce excess rather than restrain it—no one warns the wealthy to stop. Implicit is a moral economy in which fortune is unstable and self-amplifying: success tempts people into overreaching, and overreaching triggers downfall. The passage functions as a caution against greed and complacency, and as a critique of communal complicity in celebrating wealth without recognizing its perilous tendency to tip into arrogance and ruin.
