Rattlesnake round-ups are a Texan tradition. The festivals originated in the early 20th century as an attempt to reduce snake populations. Local governments, the story goes, offered a bounty to anyone who presented a dead rattler to city hall. And, as you might expect, officials were soon knee-deep in rattlesnakes – every man in town had started breeding them.
A financial incentive didn’t solve Texas’s rattlesnake problem but the story serves well to explain the consequences of Primary Health Care’s business model.
