Moral decline and Manners

There is a debate going on at the BBC about moral decline. On the One Show this evening this was discussed just from the simple standpoint of declining manners and lack of politeness (or respect). The point that they failed to acknowledge is that good manners are like high grade engine oil, they allow the normal frictions of daily life to slide by with the least wear and tear. The reality is that the more diverse our culture becomes, and the more densely our island is populated the more important good manners become. (If that's all right with you).
