The "Sunday Styles" section of The New York Times edition of 9/2/18 includes a story, Retiring at 43? You're on FIRE by Steven Kurutz.
It is about the "growing movement of young professionals who are intently focused on quitting their jobs forever". … Millennials see FIRE "as a way out of soul-sucking, time-stealing work and an economy fueled by consumerism."
The article gives a hat-tip Vicki Robin and Joe Dominguez, authors of Your Money or Your Life. Robin contrasts the voluntary simplicity movement originating in the 1990s with the current FIRE moment.
Our aim was not just to have a whole bunch of people quit their jobs. Our aim was to lower consumption to save the planet. We attracted longtime simple-living people, religious people, environmentalists.
By contrast, FIRE adherents are "very numbers oriented, fascinated by the minutiae of taxes and accounting." They are also benefiting from the lengthy bull market in stocks, and in some cases, the privilege of class, race, gender, and background. While FIRE adherents "don't have the aspirational part" of earlier generations, they feel determined to leave the paid workforce out of their needs for "...agency. The worker in this economy has very little sense of control over their existence. People are expendable. You are a young person, and you look ahead, and you say: 'What's there for me?'"
The article observes that FIRE retirees often blog about their experiences. Examples:
