Guan Zhong: If a country has lots of wealth, people from far away will come; if the land is opened up, people will stay; if the warehouses are abundant, people will know etiquette; if they have enough food and clothing, they will know honor and disgrace.

Meaning: If there are enough things in the warehouse, people will know politeness; if people have enough food and clothing, they will know honor and shame. In other words, matter is the basis of spirit.
