It is extremely important to teach our children responsibility. By showing them the value of work you can build an indispensable house hold tool/slave child. Showing your child early how to do stuff around the house will pay off quickly. I justify it simply by telling my children that 3 year olds in China make shoes for 14 hours a day, so is it really to much for me to ask for them to clean the house, cook dinner, or mow the lawn. Reinforcing an honest day of slave labor will pay off dividends in the future because by the time you need your driveway repaved they will be 8 years old and up for the challenge.
