About 7,000 ghost workers have been uncovered in Delta State civil service.
A ghost worker is a worker that collects benefits and a salary, usually from a government entity, while doing no actual work.
From Wikipedia
Delta is an oil producing state of Nigeria situated in the region known as the Niger Delta, South-South Geo-political zone with a population of 4,098,291.
The population of Delta is a little higher than that of Los Angeles, California.
So, approximately one in six hundred residents of Delta is a government worker that does not do any work. They retire and collect pensions, kicking back a portion of their compensation to their boss. This is a nuts and bolts example of how corruption works and it is a terrible drag on economic growth.
Corruption is what holds much of the developing world back. In countries whose governments are committed to the well-being of their citizens, but face corrupt and entrenched interests, biometric identity management solutions offer unprecedented corruption-fighting tools.
Moreover, the ROI (Return on Investment) is fairly straightforward to calculate. In this case, if the ID Management system costs less than 7,000 times the total lifetime compensation of a low-level government worker, it will save the state money and help it to provide the conditions for an improved standard of living for its citizens.
