From there, Georgescu’s life moved quickly. The headmaster of Phillips Exeter offered him a spot at the school even though he spoke no English and hadn’t attended any school for much of his boyhood. After college and business school, Georgescu joined the advertising firm Young & Rubicam. He spent 37 years there, the last seven as chief executive.

“The hero of my story,” Georgescu said to me “is America.” Over and over, he said, people who didn’t have any obvious reason to care about him helped him: the congresswoman who didn’t represent his parents’ district; the headmaster who’d never met him; the ad executives who mentored him.

All of them, he believes, were influenced by a post-World War II culture that (while deeply flawed in some ways) fostered a sense of community over individuality. Corporate executives didn’t pay themselves outlandish salaries. Workers enjoyed consistently rising wages.

Things began to change after the 1970s. Stakeholder capitalism — which, Georgescu says, optimized the well-being of customers, employees, shareholders and the nation — gave way to short-term shareholder-only capitalism. Profits have soared at the expense of worker pay. The wealth of the median family today is lower than two decades ago. Life expectancy has actually fallen in the last few years. Not since 2004 has a majority of Americans said they were satisfied with the country’s direction.

“Capitalism is a brilliant factory for prosperity. Brilliant,” Georgescu says. “And yet the version of capitalism we have created here works for only a minority of people.”

In his retirement, when he’s not spending time with his family, Georgescu has been trying to agitate other corporate leaders. He has published a book, called “Capitalists, Arise!” He has written op-eds and given talks. He talks about the signs of frustration, in both the United States and Europe. He has seen societies fall apart, and he thinks many people are underestimating the risks it could happen again. “We’re not that far off,” he told me.
