I frankly find it amazing that people who go to decide something once per 5 years can think they are in power.
Indeed, yes. Think how many issues we are actually voting on when we elect one party or another. Thousands of issues, and we get (a) Party A OR (b) Party B yes or no to all these issues. Once every 4 years or so (in the UK), and they're free to renege on any of these issues. And, in fact, they usually do. Most famous, I suppose, was Thatcher's campaign slogan of 1979, featuring a poster with a long queue of unemployed people with the slogan "Labour isn't working". She then gained power and made the problem 10 times worse, reaching over 4 million in official figures. The real figures were much higher.
The only way to (a) engage ordinary people and (b) to curtail the vested interests of the crooked rich is to devolve Government as much as possible to local politics.
People here don't really give a damn about what happens at the other end of the country: the south of England, for example, generally still refuses to accept the damage Thatcher did to the north. But tell people that their
local hospital is under threat or anything which affects them directly, and they're far more likely to get involved. At the moment, the mechanisms for this are few and largely ineffective.
Our political parties have something called the Whip System, a ridiculous analogy with fox hunting, where the "whipper in" can control the dogs. Whips are party members who bully, bribe and coerce MPs into voting how the party wants them to. How democratic is that? Not even slightly. MPs are supposed to represent the wishes of their constituents. We've had the sickening experience where local people do not want their local industry to go, but the MP votes for it to go simply because of the whip system. His/her career can be on the line if he doesn't tow the line.
In fact, there's so much wrong with the British political system that I hardly know where to begin. Another major problem is that ordinary people have been convinced that consensus politics and dissent within parties is actually a sign of weakness, and they hanker after "strong leadership". I think it was Lord Hailsham who called the Thatcher Governments "an elected dictatorship".
