You are totally right Pete, which I think suspending a person's license is a bunch of crap in an attempt to enforce support, but that is besides the point, it is done.
I say that because many of the people I deal with everyday do work but don't make enough to pay everything they need to pay, so they will take that chance and drive back and forth to work. Then they end up locked up for driving while suspended or driving while revoked, and what good does that do anyone? Something is better than nothing. They cannot pay when they are in jail.
But complaining about child support when you've done nothing to collect is the same as complaining about the president of the U.S. when you didn't vote. IMO Sure it is a hassle, but you have to start somewhere.
