I agree with you, MaizieD on the need for a second chamber which is not subject to the exact same influences which at any time are affecting the House of Commons. If the Commons is being swayed by populist enthusiasm for a passing fancy, then the second chamber should be immune to that. If the Commons/Cabinet is full of rich blokes whose main policy is to get even richer, the second chamber should contain people who are passionate about their careers outside politics, or their selfless work for those less fortunate than themselves, or (this won't please the keep-religion-out-of politics brigade) are concerned for the spiritual and moral health of the population, of whatever faith or none, or their physical health whether through the NHS or through other medical-type professions
I am not sure just how that could be achieved. Perhaps a quota of representatives from different professions and occupations? Then it has to be worked out how those quotas can be chosen out of their "constitiencies" of experienced workers in each category? That takes you back to elections - it is a circle!
Anyone have any workable ideas? (or even unworkable, to stimulate discussion)
