There is no pop culture anymore. The mainstream has fractured in all facets of life: music, movies, books, news, etc. Everything has become so niche, thanks to the internet, that there is no collective experience anymore—nor should there be.
People are individuals and the more individualized their interests and experiences become, the better. Why should we all be forced to watch the same TV shows because there are only four channels, or listen to the same music because there are only a handful of radio stations, or watch the same movies because the theater only shows one or two per week, or have the same worldview because there’s only one local newspaper? More choices makes life better.
The last remnant of popular culture and shared experience is politics. Everyone in the country is forced to have the same president and be ruled by the same government. But given time, the fracturing of society will extend to politics as well. People like choices in life, and in the (hopefully near) future, you will be able to choose the type of State you want to live in, be it conservative, progressive, or libertarian.
The road to this society begins with secession. Dismantle the federal government and redirect power to the states, then let them experiment and try different systems. Some will inevitably be more progressive, conservative, or libertarian, and that’s good. Let them be different and see which systems of government fair better. Best of all, individuals will have the choice to pick which State they want to live in. Don’t like liberals? Move to a conservative state. Don’t like guns? Move to a state that’s outlawed them. Want complete freedom? Move to an anarcho-capitalist state. Want full-on socialism? Move to California.
Stop arguing endlessly about politics, fighting those you disagree with, and just get a divorce. Find those you agree with and move in together. Ideally, the country will fracture further, beyond the fifty states. After all, why should people in upstate New York be ruled by the same governor as people in Manhattan? (Same with Los Angeles and San Francisco versus the rest of California.) We have a bevy of choices with just about everything else in life: food, clothes, music, TV, books, friends, jobs, etc. Why should that vast array of choices not extend to politics and government? In due time, it will.
