We can do both.  At minimum, because individuals and Churches have not stepped up (indeed, the Church does not even excommunicate Catholic business owners or share holders who refuse to supply a living wage nor does it provide it to its own workers), the state must step in.  If there were a living wage law without subsidies that required middle class sufficiency, companies would not employee people with lots of kids.  Their supply cost would be too high. Subsidiary DEMANDS governmental action.
