The Lonely Century by Noreena Hertz — English Summary

Introduction: The Century of the Lonely

Imagine paying forty dollars an hour just to have someone sit across from you in a Manhattan café and pretend to be your friend. On September 24, 2019, that's exactly what Noreena Hertz did. She met Brittany at Cha Cha Matcha in NoHo — a twenty-three-year-old Brown graduate who couldn't find work in her field, so she rented herself out through RentAFriend, a platform with over 620,000 friends for hire in dozens of countries. Brittany's typical clients? "Lonely, thirty-to-forty-year-old professionals. The kind of people who work long hours and don't seem to have time to make many friends."

This is the world Hertz wants us to see clearly. Not loneliness as a private sadness, but loneliness as the defining condition of our age — a structural symptom of how we've built our economies, our cities, our workplaces, and our lives. The book argues that the loneliness crisis is not the fault of weak individuals or lazy friendships. It is the predictable outcome of forty years of policy choices, technological shifts, and cultural drift. Unless we treat it as such, the social and political consequences will keep compounding.

Then COVID arrived. By March 31, 2020, with roughly 2.5 billion people in lockdown, the loneliness Hertz had been documenting became unignorable. German hotlines reported a fifty-percent surge in calls; one psychologist noted that callers were "more afraid of loneliness than of getting infected." A British child whispered to Childline, "My mum won't hug me." The pandemic did not create the lonely century. It simply ripped off the cover.
