Reddit reviews Rich People's Movements: Grassroots Campaigns to Untax the One Percent (Studies in Postwar American Political Development)

Have you seen Gangs of New York? There is a short scene in there about the moralizers of the upper class coming into to clean out 'dens of iniquity' and fix the 'moral problems of the lower classes' like by fighting against alcohol or drug consumption. Those sorts of movements by upper class people that see poverty as a sort of moral failing and that people could simply 'pull themselves up by their bootstraps' if they work hard enough and follow something like the Protestant work ethic are as old as time.

The modern 'SJW' type of identity politics from the upper class isn't really new, it has has a long pedigree and lets the upper classes feel less guilty about their wealth in times of increasing income/wealth inequality and poverty, as they conceptualize it being about moral failings of some kind rather than them being the recipients of the real unearned privilege and propagating the systems the not only keep it in place, but in fact deepen it.

On the right wing side of things there is also a history to try and enhance the position of wealthy through populism that this book covers: https://www.amazon.com/Rich-Peoples-Movements-Grassroots-Development/dp/0199928991

Apparently they even tried to use the women's suffrage movement at one point.
