I second the call for a brown (funny name that) paper envelope icon. There's way too much casual corruption in our system these days. I don't think there is a lot of overt corruption, but the 'we have always done it this way' gradual creep of institutionalized corruption.

Like MP's expenses as a classic example.

The Payroll Vote (look it up).

Our political system is corrupt top to bottom but it just doesn't realise it. Intellectually and morally corrupt, not so much direct bribery.
