I have no idea how to quantify the role of corruption in wealth of country, but there are obviously other factors in play. Youd have to try really hard to justify, that US is rich but corrupt, yet countries such as Nigeria or Uruguay are poor... and also corrupt.
People, who misuse public funds and their office are found around the planet.
In consumer societies the primary goal is consumption.
To "quantify the role of corruption in wealth of country", maybe important to note that what constitutes wealth is subjective. A person's "belongings" are more "a part of them" amongst consumerists. So where "wealth" is money, people do dirty tricks to get money, and where "wealth" is something else then human ambition manifests differently.
Look at all the churches where "virtue" is "wealth". People will go through all kinds of contortions and corruptions to get their wealth.
