The country that holds the record for number and percentage of people in prison is the US. In the US the percentage of black people in prison was higher than the percentage of black people in prison in South Africa during apartheid.

No other western/industrialized (at some stage) nation has had so many political exilees and people whose citizenship was revoked based on "anti-american" views than the US. At some point the general secretary of RCP was in exile in France with his citizenship revoked. So, not all states are equal, and their historic development as modern capitalist states should be studied within context.
