Most of the world is run by Europeans or European-descended (East Asian and Middle Eastern countries are somewhat influenced by the major powers of Europe and America, but largely run their own affairs).
Citizenship and participation in government is limited through some means, either property ownership, competency tests, or not being a societal burden. This prevents the government from being used by poorer classes to raise their standard of living, which always leads to waste and eventually collapse as they continually vote for more and more benefits.
The traditional roles of the sexes are voluntarily reestablished on a broad scale. Most women choose to be housewives and most men choose to be breadwinners. This shift would greatly increase the price of labor (Women entering the workforce in mass in the Western world lowered the price of labor enough that, for most families, dual income was required to live comfortably). Children, on a broad scale, are raised better, as a is mother present in the home rather than at work. It also makes homeschooling much easier for families that choose to do so.
Citizens and people at large are held to a system of honor by their peers and by themselves. Disputes are largely settled privately through discussion or duels rather than by courts.
People hold themselves to high standards in terms of work, dress, behavior, and morality.
Hobbies are much more common and much more organized. Most people belong to a club or hobby organization. Organized physical activity, such as sports organizations, are especially common.
Governments are small, mostly run by local leaders even in colonies. Tax burdens are low, and Tariffs are used sparingly.
Firearms ownership is common throughout the world, and regulation of firearms in minimal or non-existent. Competency in firearms is taught by most schools. Carrying a firearm is common practice everywhere.
Christianity is the dominant religion and most people are practicing members of Christian churches.
Pointless laws are eliminated wherever possible. Prisons are for the most part eliminated, with serious crimes, such as murder, rape, massive fraud, and corruption being punishable by death, while less severe crimes, such as theft, minor fraud, embezzling, drug dealing, and the like are punishable with fines and public humiliation.
Education is mandatory, but schooling is largely done privately, either through homeschooling or through private schools, with public schools done only on a local level.
Currencies are removed from the control of government, and transactions are done with cryptocurrency or with items such as gold, silver, or other hard assets. Secure, private, and decentralized cryptocurrency that remains stable in value replaces the U.S. dollar as the world's reserve currency.
Nuclear power becomes the dominant source of energy.
Government welfare programs are largely eliminated, with only basic food, water, and shelter being guaranteed. No money is provided through welfare programs, only the actually items required for survival. Private charity largely replaces the role of welfare.
Healthcare is taken out of the hands of government completely. Charities are formed to help those who cannot afford care. Hospitals are still required to provide emergency care to anyone who needs it. This would result in much better healthcare, even for those who are poor.
Social media is largely eliminated, with the exception of platforms adept for long-form content, such as forums and video-sharing. Long-form content is much less harmful than short-form, such as Tik-tok, Instagram, and Facebook. It also has real value in terms of education and discussion.
Wars are fought on a much smaller scale, using small, professional armies. Citizens are armed to the same degree as militaries. Many technologies and tactics are considered taboo in warfare, such as drones, cyberwarfare, genetic enhancement, etc.
Online work makes cities mostly irrelevant for white collar work, and many people move out of cities and suburbs into rural areas. Cities shrink and become mostly centers for tourism, meetings, and conferences, not places for white-collar work. People also work less, and are able to take much more time off.
Conservation is a serious concern of governments. Nature preserves are common. Hunting and fishing become very common practice. Sensible regulation and heightened awareness of nature help to ensure its preservation.
Travel is made much easier. Airline security is lessened, customs are lessened, and international regulation on items brought into countries is lessened.
Colleges and Universities are dismantled on a large scale. The remnants of higher education are in technical schools, trade schools, and professional schools. The liberal arts are relegated to lower education and individual pursuit. College degrees become irrelevant for most careers, with obvious exception for those careers that require higher degrees of technical or procedural knowledge.
Corporate media outlets are all defunct and out-of-business. News is largely reported by small, independent outlets online. Legal statutes governing libel, slander, and false reporting of events are made much harsher.
