Rooting out corruption.

Corruption.png Corruption measures a country's bureaucratic morality throughout the ranks. A country with high corruption suffers widely from embezzlement and loss of the leader's authority, while a country with no corruption is free to prosper. Unlike inflation, corruption does not directly affect monetary costs, instead affecting other areas of the state (though it may indirectly affect income due to raising the local autonomy floor of provinces).
