I'm firmly of the belief that government as we have around the world is a flawed system. When few people are given the power to rule the many, even when their mandate is one of service, that power corrupts. I believe that instead of governments we should have trade bodies, collectives that represent the people that work in their trade. These bodies decide the value of the goods they produce and trade them with others. People are, on the whole, self policing, meaning that an expensive and corrupt justice system is largely unnecessary. Instead, since the system would allow 0% unemployment, people who do wrong are punished by their peers. The most corrupting thing in our society, money, would also be unnecessary. Since the trade bodies set the value of their goods, they can negotiate fair value for what the people they represent need in exchange for what those people produce.
As for the self policing idea, since the representatives are not anything more than simply representatives, should they decide that only the purples had to work, the purples could have that person replaced immediately since there's no need to wait for an election. Of course the elderly and sick etc wouldn't have to work, 0% unemployment doesn't mean that, it means that everybody who can work, does. With a welfare system to care for those who are more vulnerable and an education system that actually teaches children things that can help them contribute to society. If group X wants something that group Y prooduces but group Y wants nothing group X produces then group Z can get involved in a trade. Similar to how multi-team trades work in baseball.
X wants timber which is produced by Y.
Y wants grain which is produced by Z.
Z wants fruit which is produceed by X.
X sends fruit to Z in exchange for grain which it then trades with Y for timber.That just means that we'll have rulers naturally selected based on their access to valuable resources and labor for which others are willing to pay highly.
The fact that the bodies are chosen by the people they represent (like a labour union) they can be replaced as soon as they are seen to be doing something their constituents don't like. (Instead of having to wait up to four years as is the case in the current system.
