The story first picked up traction on Twitter when a Boston Globe reporter posted about the incident after witnessing the aftermath of the accident on Friday.

Awful scene on the orange line. A woman’s leg got stuck in the gap between the train and the platform. It was twisted and bloody. Skin came off. She’s in agony and weeping. Just as upsetting she begged no one call an ambulance. “It’s $3000,” she wailed. “I can’t afford that.”

he story picked up more traction when The New York Times editorial board wrote about the platform accident on Monday with the headline: "This Tweet Captures the State of Health Care in America Today."

"In the face of a grave injury, a series of calculations follow: The clear and urgent need for medical attention is weighed against the uncertain and potentially monumental expense of even basic services, like a bandage or a ride to the hospital, and that cost, in turn, weighed against all the known expenses of living that run through any given head on any given day," the editorial board wrote. "This discord, between agony and arithmetic, has become America's story, too."
