Duke Ai asked Youzi, “We’ve had a famine this year and there aren’t enough revenues to run the state. What should I do?”

Youzi replied, “How about a 10% tax, as the Zhou used to levy?”

Duke Ai replied, “I can’t even get by on a 20% tax! How could I manage on 10%?”

Youzi said, “If the people have enough, you’ll have enough. But if the people don’t have enough, how can you expect to have enough?”
