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.

Garnishment is taking a portion of income, not taking the actual source of it. No business means no income, no income means no garnishment. I love how you cite Wikipedia as if grown adults here have never heard of garnishment. Then again education really is going downhill these days I guess.
