When discussing family relations it would be a great oversight not to include a discussion on finances. A wonderful and useful tool for this discussion is the pamphlet called "one for the money" written by Marvin J Ashton. these can be found on Providentliving.org under the learning to be self sufficient tab. Ashton outlines 12 principles in this pamphlet to  help families learn to manage money. Some of these principles include, paying tithing, a practice that will teach both children and parents alike to put aside money for that which is important, this could be the first form of money management that your children ever learn.
Another principle is to learn self discipline and self reliance in money matters. on this subject Ashton writes, "Money management skills should be learned together in a spirit of cooperation and love on a regular basis. A disgusted husband once said, 'I think that in life money talks, but when my wife gets hols of it, all it ever says is good bye' to the husband who says that his wife is the poorest money manager in the world I would  say, 'Look in the mirror and meet the world's poorest teacher trainer.'" as members of the same family, we should have common goals with our money and we have a responsibility to teach our loved ones how to follow that same goal.
Another piece of advice that Ashton offers is, " Married couples show genuine maturity when they think of their partners and family's needs ahead of their own spending impulses.
Ashton also points out that 80% of divorces  can be traced back to issues with money. This is a sickness contributing to the destruction of families. The  more families learn to be frugal and responsible with their funds, they happier and the more satisfied they will be in their relationships.
