I recall reading a book by Joel Kotkin that posits that the increasing inequality and class divide has a different causation than the conventional wisdom assumes. Many progressive cities (e.g. NYC, Austin, San Francisco, Seattle, Boston) are paying lip service for the disenfranchised, and yet are supporting policies that have hindered the new disenfranchised: the working/middle class. These policies have included high taxes, rent control, a maze of housing regulations/zoning laws, stringent environmental regulations that have kept certain industries away, and a NIMBY mindset for low income housing developments.
This new Left, who support such policies, includes the influential Clerisy that make up the media/academic/policy elites, as well as the tech oligarchs that have gotten a free pass from government impediments. While these are not the Wall Street bankers that often get lumped in as protest targets, they are perhaps more central to today’s power brokers in a world that is ever changing.

Not to mention, cosmopolitan cultural elites often look down and are often smug when it comes to the working/middle class. That hypocrisy doesn’t go unnoticed. In the end, it creates an anti-establishment resentment that we are now experiencing in the political events of the day.
Yes, we won’t be able to put the cultural toothpaste back into the 1950’s tube, but as Kotkin notes, there may be some hope in the mid-tier cities where the cultural elites have less prominence.
(It should be noted while increasing inequality is an empirical phenomenon, much of the perception around it is exacerbated by human nature: greedy people who don't have that much money envying greedy people who do have money. Also, if we took a deep time perspective, we all benefit from wealth generation.)
