People who have invested their life in excellence in a discipline other than politics are going to be beaten at politics by the power-hungry sociopaths who want to be politicians. So we always end up with unskilled, unethical people in government.

Ministers are (mostly) appointed from the pool of voted-for politicians, who are nearly all lawyers or politics graduates.

Well, there are hardly likely to do themselves out of a prime job, are they? But in a way they sort of do, they appoint advisers....

We could have a whole new official layer of experts, but that would be shot down by cries of bureaucracy.

Initially I like the idea of expert opinion being mandatory. So, like with the drugs advice, I would like to see government forced to adopt their proposals. But would I be happy with police experts forcing legislation? Doctors, probably, but army?

In the end, I have to come back to general population ignorance an prejudice. "We" have to smarten up, and vote accordingly. Its the only way I see.

Or in the British case at least, appoint people from the Lords who have got their through contributions to their fields.
