Only semi-related, but this reminds me of how - based on most reading I've done - social conservatism wasn't really thought of as a "populist" thing, associated with the "working class," until relatively recently. The moralist Federalist, Whigs and Republicans certainly weren't struggling to get by.
Yeah, the traditional stereotype of working-class morals was relative lack of sexual restraint. You could argue that hypocrisy has been added to that stereotype rather than the core stereotype actually changing, but it's still a pretty big shift in perceptions.
