For the sake of argument, you have five kids. You hit hard times and you are going to have to re-budget. You calculate that if you take everything away from the youngest 2 so that they have no food or clothing and you take away the clothing from the next 2, then the remaining child will not only be fed and clothed, but can actually eat out at restaurants in a new outfits every week.
As the person in charge of the budget with responsibility for the welfare of your children would you?
I think the answer is obvious really. The youngest child can go out to work cleaning chimneys, the second youngest can walk dogs, all the way up to the oldest who will go down the mine. You've got to be entrepreneurial with these things
