I like Kate Middleton, I wish her the best

she is a well put together middle class striver, and we always cheer for the breezy confidant underdog don't we?
In her fundamental outlook on life, she has to be the most American of all the commoners to marry into English Royalty.
But this notion that somehow she is importing rejuvenating go-getter values into the world's gaudiest tourist trap (AKA The House of Windsor) is sheer rubbish.
Kate is energetic and well meaning but she hasn't got a single idea worth mentioning to her preposterously inbred distant and utterly clue-less in-laws.
It'll be all Ms. Middleton can do to avoid the narcissistic fate of her late mother in law.
I'm not sure any one person can do anything to reform the British Monarchy, nobody in England wants to change the monarchy,  even as it is receding in regard and influence all over the UK.

The situation isn't sustainable, sooner or later the House of Windsor will simply vanish, probably non-violently and with little real regret on the part of their former subjects.
