Corruption

Rooting out corruption.

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).

(This can be lowered if the player chooses, although reducing expenditure will decrease the corruption reduction proportionally.)
