Our institutions are reliable. Our parliament, judiciary, civil services, while weakened by decades of under-funding, remain essentially sound and held together by great hard working people with a deep ethic of civic duty. Our electorate are pretty well educated, active and dutiful. Our elections are fair and well attended. We have a multi-chamber carefully segmented government with plenty of checks and balances to steer a path between conservative and progressive courses.
On the face of it we should have a model democracy and a prosperous nation.
But "politics" in the UK is a seedy, corrupt selection mechanism to find the worst possible human specimens and put them in power. It rewards childish, irresponsible, petulant, mean-spirited, greedy and corrupt little bullies who are vain, shallow, dishonest, weak-minded, cavalier and self-obsessed. And I'm being charitable here.
The era of the statesman is over. No matter how excellent our systems are they cannot function if staffed by incompetent hooligans.
A massive improvement to British politics could be made simply by selecting the cabinet and prime minister randomly from the population and then voting only on policies.
