If you're not British please don't assume that "ejecting heriditary nobles" from the upper house of parliament is automatically going to increase the quality of governance.

For more than a century the majority of those who sit in the House of Lords have been "Life Peers", appointed by a politician and without any heriditary aspect. They include such towers of statepersonship as : Evgeny Lebedev (Russian businessman, son of a KGB officer); Alexander Lebedev (another Russian businessman, he's actually been in the KGB); Charlotte Owen (junior aide to Boris Johnson for three years) ... the list goes on.

This isn't new (although in recent time the dodginess has risen to new highs) and many of those appointed to Life Peerages meet the goal of having significant life experience they can use to illuminate aspects of legislation that might otherwise be missed. Equally heriditary peers are not all some Wodehousian stereotype of bumbling idiots.
