I'm interested to hear that the Kaiser was astute in his handling of money - he wasn't exactly careful and discriminating in anything else!
How Wilhelm and his son handled their money might be on topic since it gives some indication of how much Georg Friedrich von Preussen might have to protect which could directly influence his choice of bride.
However, anything else about which the Kaiser may or may not have been careful or discriminating is clearly off-topic.
Is he also the guy who said, If America were to choose to negate a percieved future threat from Mexico, it would be an act of political realism and not genocide?
If Georg Friedrich von Preussen actually said this, then he must be lacking in several areas. The Kaiser would be spinning in his grave.
