The Fiefdom of Guithwine is a titanic, efficient nation, remarkable for its barren, inhospitable landscape, irreverence towards religion, and complete absence of social welfare. The hard-nosed, hard-working, democratic population of 12.832 billion Gúthwinëans are effectively ruled by a group of massive corporations, who run for political office and provide their well-off citizens with world-class goods and services. Their poorer citizens, however, are mostly starving to death while being urged to go out and get real jobs. The populace has reasonably extensive civil rights, although these are mostly aimed at allowing them to buy whatever they like.

The tiny, pro-business government juggles the competing demands of Defense, Education, and Law & Order. Citizens pay a flat income tax of 7.2%.

The thriving Guithwinean economy, worth 828 trillion bloods a year, is driven almost entirely by the private sector, which is broadly diversified and led by the Gambling industry, with significant contributions from Book Publishing, Retail, and Woodchip Exports. Average income is 64,529 bloods, but there is a significant disparity between incomes, with the richest 10% of citizens earning 228,413 per year while the poor average 13,162, a ratio of 17.4 to 1.

A large-scale revitalization of the education system is underway, the latest Harry Potter book is a bestseller, military spending is on the increase, and voting is voluntary. Crime is moderate, with the police force struggling against a lack of funding and a high mortality rate. Guithwine's national animal is the Horse obviously, which can occasionally be seen sifting through garbage in the nation's cities.

Guithwine is ranked 293,618^th in the world and 200^th in ainulindale for Most Eco-Friendly Governments, scoring -4.47 on the Dolphin Recycling Awareness Index.
