"The author R. R. Reno has argued that what we're really facing these days is a 'crisis of solidarity.' Many people, as the writers David and Amber Lapp note, feel pervasively betrayed: by for-profit job-training outfits that left them awash in debt, by spouses and stepparents, by people who collect federal benefits but don't work. They've stopped even expecting loyalty from their employers. The big flashing lights say: NO TRUST. That leads to an everyone-out-for-himself mentality and Trump's politics of suspicion. We'll need a communitarianism."
David Brooks in The New York Times attempts to understand why he did not anticipate Donald Trump's popularity.
