Democracy - the worst system of Government except all the others.

All power to critics every politician needs them on their shouldres all the time.

Not voting - hard to see what it achieves.

Voting is not enough. If your care about democracy and you feel able to contribute, the place is inside current politcal parties. Many of Tony Blairs critics are inside the party. The rank and file are not happy people.

If you want to actually change things, that's the best place to work.
