The issue with child support is that the state child support agencies often rely on bureau of labor figures to determine what someone with a particular job "should" be making, and don't consider variance in wages or cost of living when levying child support rates. So while the payments might be reasonable according to some bureaucrats rule book, they aren't reasonable in the real world (a common issue is men with large child support obligations wanting to start another family). There have been numerous cases of actors whose child support obligations were set at the peak of their career and yet the CSA still expects them to be making the same money.
