Much of this varies by state.
I believe NYC recently stated the cost of a family of 4 on public assistance (section 8, WIC, EBT, Free Subway rides, free wi fi, Obamaphones, free cell service, Medicaid, free school lunch free school breakfast, in NYC the schools wash most students clothing, free summer meals when school is closed, free heat, free electricity, free college applications, free college, free primary & high school, free prescriptions, free dental, free legal, free mental health, free transportation to/from jails and a host of other free programs) the city claims this has a value of $120,000 for that family.
That value and the benefits vary from state to state
