It's certainly true that managers are lazy and they would rather measure illusory proxies for work rather than work itself, but America also became a major economic engine of the world by exerting control over people's bodies without paying them. Even though that practice ended several generations ago, the attitude that equates "success" with "power over bodies" is still very common in America. Many states are now trying very hard (again) to control women's bodies with the force of law, to cite just one example.
