How socialism works

So, Tony Benn wants to be selected for the unwinnable Conservative seat of Kensington. What that man will never cease to do to bolster his own self-importance, er, represent the cause of the common people, eh?

Last week came the news that some seventeen year old - who just happened to be a granddaughter of the self-styled saviour of the Party - was selected to fight the seat of East Worthing and Shoreham. RecessMonkey claimed, rather nauseatingly in Westmonster's view, that this would be a Good Thing because, well, she is a Benn. Niece of Hilary, granddaughter of Tony, great granddaughter of William (also an MP), and great-great granddaughter of two further MPs.

Two questions: first, why did Labour get rid of the hereditary principle in the House of Lords in the first place if they're going to allow it to continue in the Commons; second, isn't it a bit rich given this to criticise David Cameron for being a lightweight posho if any berk with the right moniker can advance faster than the proles in the so-called party of equality?
