High level corruption refers to misconduct at the top and by leading politicians.
Since these people are generally well-off and have a lot of privileges associated with
their high office, their corrupt behaviour is not attributable to low pay and out of
necessity to meet the living expenses of their families. Instead, greed is considered a
main motivating factor. But there are other compulsions. To remain in office, for
example, can also be an overriding motivating force. With election campaigns
becoming expensive, corruption related to campaign financing is a big political issue
in some countries.
