Why do dead beat dads always get away with not paying?

How come when a man chooses not to help support the child/ren that he helped create it is always up to the mother to figure out how to take care of the kids? How come the father can just go about his life like no one else matters and work underneath the table or not work at all and its ok. The courts never even really try to get the father to pay. They just say you have to wait until he gets a job. And when he doesn't, it takes months and months to suspend his license and months and months for anything else. (if they even decide to do anything) Meanwhile, the mother is working numerous jobs and struggling the whole time, while he is spending his money how ever he sees fit and not worrying about having to help. What kind of world are we living in? Its no wonder we have so many children today without fathers and In trouble. And so many mothers that cant provide the proper kind of life for their children. If the judicial system would just step it up and set some new guidelines we wouldn't have this problem. I think because there is no real structure to child support so many families are falling through the cracks and our kids are the ones who ultimately pay the price. Im disgusted...any thought or insights?
