Rounding Up Deadbeat Parents

Why is it so easy to find deadbeat fathers and moms but can not collect a dime? I think that in some case trying to squeeze blood from a turnip, is just not going to happen. The ideal to impose child support on a person who is living with his mom and then put him in jail, what is that really going to accomplish... In my mind repeat offenders usually have a hard time finding work. So even if its only 50 dollars a month, something is better than nothing. To impose a fine and take half of a mans check is not fair to the man or his family. You see until the judges start looking at what they do to the common man, they will never know how to be fair and impartial. So in 6 months they will have another round up.
