The BB Spice Must Flow Puppet of Mentat Jon is a gargantuan, efficient nation, renowned for its multi-spousal wedding ceremonies, punitive income tax rates, and compulsory gun ownership. The hard-nosed, hard-working, devout population of 26.561 billion Mentat Jonians are either ruled by a sleek, efficient government or a conglomerate of multinational corporations; it's difficult to tell which.

The large government juggles the competing demands of Defense, Law & Order, and Spirituality. It meets to discuss matters of state in the capital city of The Mentat training city. Citizens pay a flat income tax of 57.9%.

The thriving Mentat Jonian economy, worth a remarkable 1,963 trillion Spices a year, is broadly diversified and led by the Arms Manufacturing industry, with major contributions from Retail, Beef-Based Agriculture, and Basket Weaving. Average income is 73,920 Spices, but there is a significant disparity between incomes, with the richest 10% of citizens earning 227,055 per year while the poor average 18,608, a ratio of 12.2 to 1.

The government baselessly accuses foreign dignitaries of being assassins, victims of crime are viewed as less trustworthy than politicians, former school buses now regularly shuttle kids to the nearest shopping centers to work, and soldiers' positions are given away by the glint of their bayonets. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Mentat Jon's national animal is the Sand Worm, which is also the nation's favorite main course, and its national religion is Knowledge.

Mentat Jon is ranked 67,410^th in the world and 5^th in Dune for Most Patriotic, with 20.89 flags saluted per person per day.
