I've seen Dungeons, but no modern Prisons or Penitentiaries (although, to be honest, with 6 Feb Release coming so soon I've stopped watching for specific 'reveals' in the last coupe of weeks).
Also, have not seen anything linking 'Extra Production' to either Dungeons or any other Forced Labor structure.
Realizing that Work Camps, forced labor institutions and chain gangs have really negative connections in the 20th century: an in-game mechanic called 'Slave Labor' or 'Gulag' will probably not do sales any good anywhere, even if they are appropriate for certain government-types, like Fascist, Communist or (American) Democracy.
