Public recordings - not just minutes, but actual video and audio - of all significant ministerial and financial meetings would go a long way to restoring real accountability.

Do you really think it would work, even if desirable (I don't think it is)? Don't you think that, the minute after they start recording these meetings, participant will stop saying anything significant and shift to backroom deals for the real stuff and decision-making? Unless you implant microphones and micro-cameras on all the politicians and civil servants (and CEOs while we are at it), you won't be able to monitor them properly...

"People only accept change when they are faced with necessity, and only recognize necessity when a crisis is upon them." - Jean Monnet
