The Prophets and Work

Sometimes, God uses the decrease production relative to amount of toil to get a person's or a people's attention. See Haggai 3:15-17

Now then, consider from this day onward. Before stone was placed upon stone in the temple of the Lord, how did you fare? When one came to a heap of twenty measures, there were but ten. When one came to the wine vat to draw fifty measures, there were but twenty. I struck you and all the products of your toil with blight and mildew and with hail, yet you did not run to me, declares the Lord.
