I seriously doubt that /everyone/ would be on the 'free everything' plans. Just like right now not /everyone/ is in jail (but those that are still cost us QUITE a bit both in jail fees and in public court fees of various kinds).

Wouldn't a social safety net to prevent destroyed families, to prevent crimes driven by desperation and/or drug abuse, and to fund the enrichment of workers in to higher skill cogs in the machine that is society be a wiser investment than in more police, prosecutors and jails?
