We have a system suggested by DS psychologist, that I also saw on 1-2-3 Magic.

Basically they get 20c per year of age (this amount can change, mine are little so $1 seems a lot to them ), regardless of what they do. We have certain expectations taht they are part of this house, so should help out, so they are expected to take their plates from the table to the dishwasher, DS to empty dishwashers, DD to set the table at night, and for them both to take their bags in from the car. If they don't do these things, that is fine, I will, but I charge for my time, because my time is valuable too. I charge between 5 - 10 cents to do 1 of their jobs. I have only had to charge each of them once and they never did it again (although sometimes I do things like take their brekky stuff over once they have left for school if I didn't notice it before they leave, but thats 'cos I don't want it sitting there all day, and they are only little). The thought of having to part with their money kills them, so it gets them back to do their job (they normally get 1 warning before I do it).

I agree $60 is way too much, and I think it lowers their sense of self-purpose to be paid for such menial jobs. They need to learn that they have to contribute for the very fact they are part of a family.
