Life would be simpler if morally objectionable things like corruption also had unambiguously negative economic consequences

Life would be simpler if morally objectionable things like corruption also had unambiguously negative economic consequences. But the reality is a lot messier. Looking at just the last half a century, there are certainly countries, like Zaire under Mobutu or Haiti under Duvalier, whose economy was ruined by rampant corruption. At the other extreme, we have countries like Finland, Sweden and Singapore, which are known for their cleanliness and have also done very well economically. Then we have countries like Indonesia that were very corrupt but performed well economically. Some other countries - Italy, Japan, Korea, Taiwan and China come to mind—have done even better than Indonesia during this period, despite ingrained corruption on a widespread and often massive scale (though not as serious as in Indonesia).
