The elephant in the room in West Africa, so to speak, and the suppression of piracy is corruption.
If one takes the most recent World Bank scores for (1) government effectiveness, (2) regulatory quality, (3) rule of law, (4) control of corruption, and (5) political stability, and normalizes their means for equal comparison by state, then multiplies these means by the normalized reciprocal of Transparency International’s latest Perceived Corruption Index, which works in the scalar opposite direction, the results are overwhelmingly depressing. The multiplication by the normalized corruption score is valid because corruption pervades all the dimensions the World Bank measures.
On a scale of 1-100, here is what comes out. Each score is the rank above zero compared to all states. Zero can be defined as nearing ungovernability with concomitant complete corruption.
