Kleptocracies are generally associated with dictatorships, oligarchies, military juntas, or other forms of autocratic and nepotist governments in which external oversight is impossible or does not exist. This lack of oversight can be caused or exacerbated by the ability of the kleptocratic officials to control both the supply of public funds and the means of disbursal for those funds. Kleptocratic rulers often treat their country's treasury as a source of personal wealth, spending funds on luxury goods and extravagances as they see fit. Many kleptocratic rulers secretly transfer public funds into hidden personal numbered bank accounts in foreign countries to provide for themselves if removed from power.
Kleptocracy is most common in developing countries whose economies are based on the export of natural resources. Such export incomes constitute a form of economic rent and are easier to siphon off without causing the income to decrease.
A specific case of kleptocracy is Raubwirtschaft, German for "plunder economy" or "rapine economy", where the whole economy of the state is based on robbery, looting and plundering the conquered territories. Such states are either in continuous warfare with their neighbours or they simply milk their subjects as long as they have any taxable assets. Arnold Toynbee has claimed the Roman Empire was a Raubwirtschaft.
The effects of a kleptocratic regime or government on a nation are typically adverse in regards to the welfare of the state's economy, political affairs, and civil rights. Kleptocratic governance typically ruins prospects of foreign investment and drastically weakens the domestic market and cross-border trade. As kleptocracies often embezzle money from their citizens by misusing funds derived from tax payments, or engage heavily in money laundering schemes, they tend to heavily degrade quality of life for citizens.
In addition, the money that kleptocrats steal is diverted from funds earmarked for public amenities such as the building of hospitals, schools, roads, parks – having further adverse effects on the quality of life of citizens. The informal oligarchy that results from a kleptocratic elite subverts democracy (or any other political format).
According to at least one commentator, parasitism may be the new social paradigm — involving class warfare and exploitation of electoral processes — of myriad and disparate countries around the world. See Oligarchy and Elite capture.
