Last night, after reading my all time favorite book to DD8 ("A High Price to Pay" by Joy Berry), DD8 told me "I want to make some money! How can I earn some money?" Then she asked "Would you pay me for chores?"
I still owe her an answer. DD8 gets an allowance of $2.50/week, no strings attached. She has no regular chores. She usually gets some money for her birthday and Christmas from my side of the family. We do not pay her for good grades. She doesn't spend her money, anyway... She has a "long term financial goal": She wants a convertible. So far, she has saved up almost $600.
I feel that we are a family, not a business. I expect her to do chores as requested because she is part of this family. On the other hand: I don't want her to go out and get a job, either (I doubt that anybody would hire her for yard work or as a mother's helper at her age anyway). To be honest: The whole thing feels strange. What 8-year-old saves up for a car?! 
Are you paying for chores or/and help/support your child getting "a job"?
