The Praetorian Republic of Arcomo is a titanic, efficient nation, ruled by Diederick Antonius with an even hand, and renowned for its soft-spoken computers, ban on automobiles, and punitive income tax rates. The compassionate, cheerful population of 17.68 billion Arcomen enjoy extensive civil rights and enjoy a level of social equality free from the usual accompanying government corruption.

The enormous, liberal, socially-minded government prioritizes Education, although Environment, Social Policy, and Healthcare are also considered important, while Spirituality is ignored. It meets to discuss matters of state in the capital city of Utopiapolis. The income tax rate is 100%.

The frighteningly efficient Arcoman economy, worth a remarkable 4,240 trillion aureis a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is highly specialized, is led by the Tourism industry, with major contributions from Information Technology and Book Publishing. Average income is an amazing 239,851 aureis, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Saturday morning cartoons feature full frontal nudity, the constant playing of Merry Birthday on Arcoman radio has led to calls for the song to be classified as a crime against humanity, the nation's atlases tend to go out of date every few weeks, and Diederick Antonius's new door-knocking campaign has the sweet taste of success. Crime is totally unknown. Arcomo's national animal is the Grizzly Bear, which frolics freely in the nation's many lush forests.

Arcomo is ranked 6,093^rd in the world and 11^th in The Social Liberal Union for Most Scientifically Advanced, scoring 515.11 on the Kurzweil Singularity Index.
