It has to be admitted that Donald Trump is doing exactly what he was elected to do.He was not elected to be a legislative president. He never showed any real interest in policy during the campaign. Hewas elected to be a cultural president. Hewas elected to shred the dominant American culture and to give voice to those who felt voiceless in that culture. He’s doing that every day.What’s troubling to me is that those who are the targets of his assaults seem to have no clue about what is going on. When they feel the most righteous, like this past weekend, they are actually losing and in the most peril.Let me try to explain what I think is happening:World War II the Protestant establishment dominated the high groundof American culture and politics. That establishment eventually failed. It tolerated segregation and sexism, led thenation into war in Vietnam and became stultifying.So in the late 1960s along came a group of provocateurs like Abbie Hoffman, JerryRubin and the rest of the counterculture to upend the Protestant establishment. People like Hoffman were buffoons, but also masters of political theater.They never attracted majority support for their antics, but they didn’t have to. All they had to do was provoke, offend the crew-cut crowd, generate outrage and setoff a cycle that ripped apart the cultural consensus.The late 1960s were a time of intense cultural conflict, which left a lot of wreckage in its wake. But eventually a new establishment came into being, which we will call the meritocratic establishment.These were the tame heirs to Hoffman and Rubin. They were well educated. They cut their moral teeth on the civil rights and feminist movements. They embraced economic, social and moral individualism. They came to dominate the institutions of American society on both left and right.Hillary Clinton is part of this more educated cohort. So are parts of the conservative establishment. If you’re reading this newspaper, you probably are, too, as am I.This establishment, too, has had its failures. It created an economy that benefits itself and leaves everybody else out. It led America into war in Iraq and sent the working class off to fight it. It has developed its own brand of cultural snobbery. Its media, film and music industries make members of the working class feel invisible and disrespected.So in 2016, members of the outraged working class elected their own Abbie Hoffman as president. Trump is not good at much, but he is wickedly good at sticking his thumb in the eye of the educated elites. He doesn’t have to build a new culture, or even attract a majority. He just has to tear down the old one.That’s exactly what he’s doing. Donald Trump came into a segmenting culture and he is further tearing apart every fissure. He has a nose for every wound in the body politic and day after day he sticks a red-hot poker in one wound or another and rips it open.Day by day Trump is turning us into a nation of different planets. Each planet feels more righteous about itself and is more isolated from and offended by the other planets.The members of the educated class saw this past weekend’s N.F.L. fracas as a fight over racism. They felt mobilized andunified in that fight and full of righteous energy. Members of the working class saw the fracas as a fight about American identity. They saw Pittsburgh Steelers coach Mike Tomlin try to dissuade Alejandro Villanueva, a three-time combat veteran, from celebrating the flaghe risked his life for. Members of this class also felt mobilized, unified and full of righteous energy.I don’t know which planet is bigger, or which would win an election, but that frankly doesn’t matter. All that matters is that Trump is shredding the culture and ending the dominance of the meritocraticestablishment.He continually goes after racial matters inpart because he’s a bigot but also in part because multiculturalism is the theology of the educated class and it’s the leverage point he can most effectively use to isolate the educated class from everyone else.He is so destructive because his enemieshelp him. He ramps up the aggression. His enemies ramp it up more, to preserve their own dignity. But the ensuing cultural violence only serves Trump’s long-term destructive purpose. America is seeing nearly as much cultural conflict as it did in the late 1960s. It’s quite possible that after four years of this Trump will have effectively destroyed the prevailing culture. The reign of the meritocratic establishment will be just as over as the reign of the Protestant establishment now is.Of course Donald Trump is a buffoon. Buffoonery is his most effective weapon. Because of him, a new culture will have to be built, new values promulgated and anew social fabric will have to be woven, one that brings the different planets back into relation with one another.That’s the work of the next 20 years.
