Do you have a belief that politicians somehow do know these things well enough to make decisions across this spectrum on your behalf?
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.
