This is already a requirement for mothers to receive support from the state.  And, the father (or mother) is required to pay the state  back for supporting their children.  Able bodied parents must seek employment and report their progress.  And yes, there are parents who would appreciate working and learning on the job, if required to repay the assistance they have.  But, that would mean that somebody's job with the government would be cut-back?  Such work programs were once available through a government funded initiative...it was not supported by government workers.
