Depending on your viewpoint, money may or may not be seen as corrupt.
If we look at money and the financial system as representation and quantification of trust between people which exists to enhance the flow of that trust, then we can say that modern money and modern financial systems corrupt that noble ideal to some degree.
Nothing is perfect, and money systems are definitely not perfect. They have design flaws, implementation flaws, and they are not immune to manipulation.
Yet, as a tool, money cannot be corrupt. A tool can be adequate or inadequate, efficient or not efficient. It is only the integrity of people which can be corrupted.
To prevent both the corruption of people and the use of inadequate tools, all people should strive for a much more comprehensive financial education - corrupt money should be a thing of the past.
