The Commonwealth of Sen Jast is a massive, efficient nation, ruled by Mario Neta with an even hand, and renowned for its pith helmet sales, free-roaming dinosaurs, and devotion to social welfare. The compassionate, hard-working population of 1.293 billion Sen Jastians have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The medium-sized government is primarily concerned with Education, although Industry, Law & Order, and Healthcare are also considered important, while Spirituality and International Aid receive no funds. It meets to discuss matters of state in the capital city of Miranda City. Citizens pay a flat income tax of 29.1%.

The frighteningly efficient Sen Jastian economy, worth 156 trillion jasts a year, is fairly diversified and led by the Information Technology industry, with major contributions from Tourism, Beef-Based Agriculture, and Book Publishing. Average income is an impressive 121,204 jasts, with the richest citizens earning 9.8 times as much as the poorest.

Economic output is rising as the chronically depressed are persuaded not to burden society, peace talks occasionally rack up a higher body count than the wars they seek to stop, 'A is for Annulment' is a popular children's song, and the government is denying reports that criminals injected with experimental drugs have turned into monstrous supervillains. Crime, especially youth-related, is totally unknown, thanks to a capable police force and progressive social policies in education and welfare. Sen Jast's national animal is the wolf, which frolics freely in the nation's many lush forests, and its national religion is Agnostic.

Sen Jast is ranked 94,757^th in the world and 3,686^th in The East Pacific for Lowest Overall Tax Burden, scoring 56.14 on the Hayek Index.
