It was designed so that wealthy landowners could attend sessions more easily. Just like the u.s. senate does not represent the population, but the land area. The writers of the national and state constitutions were almost all wealthy landowners.
In my opinion, given the size of the population and the complexity of the economy, full time politicians who are paid very well combined with draconian anti-graft laws are needed.
Dude, everyone I show this too loves this feature. It's such a simple solution to an ongoing issue.
