That's essentially what a ballot paper is, except the questionnaire is "Which political party have the Red-top or Black-top newspapers convinced you to vote for?" - and I think history demonstrates that a population cannot reliably vote for their own best-interests - so expecting them to produce reliable aggregate data through mass surveys - with which to make major decisions, is foolish.
Take the TPP for example. Is it a good idea? Is it bad? I haven't read it, and even if I did, I probably wouldn't know either way. Even if I could vote on it directly, I'd have to trust someone to explain it to me. And how would I know which explanation to trust? It seems that we're back to square one.
Most of our politicians know precisely fuck all about the cabinet offices they inhabit.
Meanwhile, Hunt, the culture secretary for the Olympics did such a great job that he is now the Health Secretary.
I would rather get a 1% tax increase, and pay for real people, a real NHS manager with 50 years, and pay him for his insight than pay these fucking plebs to poke around in their careers.
Edit: that isn't "regressive" as leftists confusingly redefine it, it's the dictionary definition. Might be important to note in a political comment.
