What does Deuteronomy 28:29 mean?

You’ll grope around in the middle of the day like someone blind in the dark. Nothing you try will work out. You’ll be constantly cheated and robbed, and no one will help you. Deuteronomy 28:29 - Modern Text Bible

(This verse paints a picture of total helplessness and injustice, where people are lost and vulnerable, and society breaks down.)
