As I said to someone else, taking some feasible payment from income is different from rendering someone unemployed. If you took a construction worker's tools, a taxi drivers car, or anything like that, then you put them out of business and render them incapable of paying. As far as divorce or child support, the same principle applies (or ought to). If the worker cannot sustain himself and his necessary expenses, he will become unemployed and incapable of paying.

Well, the catch is, you may not like what the judge decides is feasible. At least in the divorce cases the interests of the parties have to be balanced, here they don't have to be.
