A consequence of democracy means average people get a vote.

However average people are actually pretty good at making the right moral, common sense calls, if not the technical legal detail. I suspect that's in part because they are not living in the Westminister ( or whatever your seat of power is ) bubble.

So any system needs to blend that common sense, with specific expertise. In theory that's what a representative democracy does - however one of the failings currently is the party system ( note designed, in part, to overcome the bandwidth problem - people grouping together to give a single consistent message rather than 100's of independent ones ), where capture of the party by a few people has become too easy and some options that the majority of people want never being offered at the voting time.

This results in an increasingly angry and volatile electorate.
