By the Sweat of Thy Brow

Teach them TO SERVE.  In order to Serve, they have to know how to work.
Training Self-Reliance and Service is an INVESTMENT.

"BY THE SWEAT OF THY BROW THOU SHALT EAT THY BREAD, 

ALL THE DAYS OF THY LIFE."

Instead of earning money for their work, 

I've divided up their chores throughout the day to earn each meal.

Food is a great motivator.

For example, to earn breakfast= get ready, housework, help cook

lunch= clean up toys, make lunch

dinner= homework/yardwork, laundry/bath, help cook

dessert= help clean up kitchen after dinner

(They still have a chance to earn money by passing off talents or doing extra chores)
