The United States of Mesozoic is a colossal, socially progressive nation, ruled by President Enzo Semedo with a fair hand, and notable for its museums and concert halls, ubiquitous missile silos, and multi-spousal wedding ceremonies. The compassionate, democratic, devout population of 3.34 billion Mesozoicans 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 medium-sized government juggles the competing demands of Education, Administration, and Industry. It meets to discuss matters of state in the capital city of Mesozalia. The average income tax rate is 76.6%, and even higher for the wealthy.

The frighteningly efficient Mesozoican economy, worth 611 trillion Mesozoican dollars a year, is broadly diversified and led by the Information Technology industry, with major contributions from Tourism, Book Publishing, and Retail. Average income is an impressive 183,004 Mesozoican dollars, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Flipping a coin to make a decision leads to a referral to Gambling Addiction Services, kids these days know how to throw a proper punch, a video of President Enzo Semedo wearing shock-blue face paint and smashing an electric guitar in front of a frenzied crowd is on endless repeat on the nightly news, and military officers are given medals for disobeying orders. Crime, especially youth-related, is totally unknown, thanks to a well-funded police force and progressive social policies in education and welfare. Mesozoic's national animal is the white-tailed eagle, which soars majestically through the nation's famously clear skies.

Mesozoic is ranked 22,082^nd in the world and 7^th in North America for Highest Average Tax Rates, with 76.58 Effective Tax Rate.
