In recent weeks, calls have abounded to pay more than lip service to women’s contributions to the global economy. Suddenly we are hearing more about the female face of essential workers — both on the homefront and on the front lines of the coronavirus pandemic. The crisis has shown, again and again, “women’s work” — otherwise known as the care economy — is essential work. Yet laud it though we might, care work is all too often unpaid and consistently among the lowest-paid job categories. Economists estimate that women’s unpaid work provides a subsidy to the global economy of more than $10 trillion annually. That’s bigger than the nominal GDP of India, the U.K. and France combined. And that’s a conservative estimate.
