Can anyone explain the math involved in child support payments? How is it that a father can be told by the state to pay $225 a month for two kids when the mother  makes less than he does and has the children 5 nights/week, and also pays for 90% of their food, 75% of their clothing, all of their incidentals (e.g., toothpaste, birthday gifts, violin rental, laundry detergent) and does 95% of the work involved in keeping them going, e.g.,  appearing civilized and moderately groomed, getting their homework done, arriving in the right place at somewhat the right time. It seems to me that the courts ASSUME that somehow the mother will come up with the rest of the money that the $225 does not cover in monthly expenses — whether it means borrowing or working crap jobs that take her away from her kids or renting out more and more of her house. How this adds up to make any kind of sense whatsoever is beyond me.
