Corruption is a real concern. No country in the world is free of corruption. Reducing it to the most minimal level requires a multi-pronged approach, including paying civil servants decently, setting a good culture, having oversight where people check other people’s work (anonymously to avoid intimidation or collusion) and lots of other things. It’s not a simple fix.

Corruption is not a curse that is particular to the public-sector. Economies with private ownership are also prone to corruption: Lehman Brothers, Enron, etc.
