A couple of good questions that have come to my notice recently

In various online forums I've seen the following questions posed recently:

• what is the steelman defence of the Christian belief in "turning the other cheek"? or indeed of that same principle when dissociated from Christianity?
• is it possible, and if so how, signficantly to increase the economic practicality of single income nuclear families, whether traditional in constitution or otherwise
• whether it is sinful or otherwise wrong not to strive for a higher standard of living if one is providing for one's family
