a better idea would be free education for all high school graduates, up to 4 yeas.  this way, they can earn a degree or skill and likely obtain a good paying job.  like the proverbial saying, you can give a man a fish to eat, but if you teach him how to fish, you feed him for a lifetime.  if only favor giving welfare to those who are truly destitute but not able bodied people - they need to work and contribute to society.
