The problem of using Switzerland as a yardstick is that barely any population anywhere can match up maturity and morality of them, maybe some nordics. Give a glimpse of same freedom/responsibility to otherwise mature British folks and we have brexit.
US has many fine things running for it, but politics (and healthcare, education, criminality etc) definitely ain't it and should not be taken as inspiration. The whole us-vs-them mentality that such longterm bipartisan system brings is very limiting. What if I like low taxes, while also supporting abortions and legal soft drugs? Or any other mix that would be pretty schizophrenic in US.
GP isn't talking about direct democracy but their governing cabinet which is basically how governing cabinets in the majority of Europe are formed.
I don't think that's fair, both to nordics and to British folks. People are mature because the system treats them as mature. If the system obviously has contempt for you and everyone like you, then of course you will act out like a youngest child.
