"Corruption", term is a social evil. wealth is a symptom of corruption. not everyone can keep a level head and use it wisely (investments, pay off debt, etc.) they go crazy buying things they think they need, lots of electronics and toys and what not. a documentary showed how a couple won the lottery and it destroyed their relationship. they ended up breaking up and the guy became a priest and the woman rescued animals.
Party subversion on behalf of other parties - i.e; the act of getting a republican to pose as a democrat, or a democrat as a republican, can be considered to be an example of corruption.
