Across this chain of seaside villages comprising some of the most expensive real estate in the world, many of the migrant laborers who maintain the scenery cannot afford to live within it. The lucky ones rent a cuarto — a room inside a house crowded with other workers — for $800 to $1,000 a month. In winter, when landscaping work dries up, even that becomes out of reach for several dozen laborers, shelter workers and outreach staff say. “It broke me to realize that in the Hamptons, plants are covered for the winter while people are left outside in the cold with nothing,” said Marit Molin, a licensed clinical social worker and the founder of Hamptons Community Outreach. “Like most other people, you think of the Hamptons as this place that’s lavish.” Above: Leaving tent to go to work.
