The number of instances that a typical American will need to be ‘humble and obedient’ - such as while getting pulled over by a cop, are possibly far fewer than the number of instances a woman in a traditional society such as the one described by Haidt is required to do so.
Possibly by an order of magnitude.
Heh, was just about to post that I as an Indian woman who has done a fair bit of travelling around the country have NEVER ever seen this, but decided to google just in case. And found a New York Times article agreeing with the claim. Upper class privilege indeed. :)
In any case this doesn’t look like an institutional policy, just petty corruption against those who are the least powerless to stop it. Which is sort of your point.
