The Sweet Dominion of Kaywinnet is a titanic, genial nation, ruled by Kaywinnet Lee with a fair hand, and notable for its free-roaming dinosaurs, punitive income tax rates, and devotion to social welfare. The compassionate, democratic, devout population of 11.142 billion Kaylees love a good election, and the government gives them plenty of them. Universities tend to be full of students debating the merits of various civil and political rights, while businesses are tightly regulated and the wealthy viewed with suspicion.

The enormous government juggles the competing demands of Administration, Education, and Welfare. It meets to discuss matters of state in the capital city of Serenity. The average income tax rate is 70.7%, and even higher for the wealthy.

The large but inefficient Kaywinnetian economy, worth 451 trillion jewels a year, is driven entirely by a combination of government and state-owned industry, with private enterprise illegal. The industrial sector, which is quite specialized, is led by the Uranium Mining industry, with major contributions from Pizza Delivery, Information Technology, and Soda Sales. Average income is 40,486 jewels, and distributed extremely evenly, with practically no difference between the richest and poorest citizens.

Parents are always up to speed on the latest childcare techniques, bus ads propagandize causes ranging from sexual revolution to religious pogroms, programmes of questionable content are shown at peak-hours, and government-sponsored gallows are being erected by Violetist temples. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Kaywinnet's national animal is the macaque, which frolics freely in the nation's many lush forests.

Kaywinnet is ranked 82,072^nd in the world and 3^rd in Firefly for Most Scientifically Advanced, scoring 116.85 on the Kurzweil Singularity Index.
