The US has the highest real incarceration per capita on the planet except Seychelles, mostly for nonviolent crimes that were instituted (War on Drugs) by Nixon to attack the poor, minorities and other “opponents.” Also consider the number of for-profit prisons and the prison industrial complex that runs transportation, staffing and internal services for the public prisons.

It’s also worth carefully re-reading the text of the 13th amendment. The giant slavery loophole is as-intended. The Union lost the Civil War while it got to declare “Mission Accomplished” because Abraham Lincoln sold-out civil society. Slavery continues as corporations profit by exploiting cheap labor paid on average under $1/hour. Systematic disenfranchisement is profitable.
