Basically there is a very specific class of people who consider themselves and eachother "influencers". Not rich enough in wealth or skill or power to be considered powerful on a real world level, but rich enough and with an amplified enough voice by either media or academia to convince themselves that they hold sway over society and are thus destined to shape it in their own image, destroy what they declare to be social evils, and eventually rally the grateful proles and overthrow those who actually hold power in some nebulous way. Think a more hipster version of "the middle" from goldstein's book in 1984.
These people are near universally formed of those born with a silver spoon up their ass to a greater or lesser extent, with rich parents, trust funds, family connections aplenty, and whom go into various forms of media thinking it will get them the "real" power and influence they think their genius warrants them with minimum effort and graft on their part. Self made men and women from the working and middle classes might occasionally be naive enough to believe that this idiot fringe is where true power lies, but overwhelmingly this class will be formed of and by those born into money and privilege who are simultaneously narcissistic and naive enough to believe that they are "destined for greatness" without needing to work for it.
They invariably band together with like minded pompous authoritarian brats in their field and beyond, latch on to a "trendy" dogma or cause they can use to present themselves as morally perfect crusaders against inequity, and use their combined numbers and wealth and power within media/academia to intimidate everyone else there into toeing the line for fear of destroying their careers and lives, often gaining total control of media institutions and organisations or college campuses, despite only representing a minority within these organisations.
Those who hold actual power care nothing for them and their demagoguery, but do buy into the assumption that they do hold influence over the proles and thus should be courted and ostensibly pandered to in order to ensure their own operations and political games keep going without interference, sometimes abandoning any notion of trying to win over the proles in favour of much more relateable and rich influencers.
Where the "bubble" part of this comes into effect is the fact that while they are obsessed with coercing outsiders to submit to their way of doing things, they are utterly blind and ignorant to how those outside their petty fiefdoms actually live, think, and function, never rising beyond the inbuilt assumption that they themselves represent the vast majority and that whatever they do will receive nothing but cheers of admiration from the peasants. They spend their lives from cradle to grave surrounded either by pampered moderately rich people in their media cliques, or by pampered moderately rich people trying not to incur their wrath for the sake of their careers. They receive nothing but positive affirmation from all IRL directions no matter how hilariously they are fucking up.
Thus when they meet not only determined resistance but active criticism and mockery from groups of proles, their first and only solution is to declare them subhuman hate filled vermin who want nothing more than to rape and murder them and their families, and to enslave society in a depraved nightmare world, and use their interlinking media/academia circlejerks to rapidly have them denounced across the media as dangerous monsters. After all, they know that they and their friends are perfect, so only the most despicably evil or stupid reprobate could dare to attack them. Never quite understanding how fucking stupid this looked to the majority of proles, or how much of a fanatical societal backlash against them and their cause will be incited by their idiocy.
Once this backlash starts, some of the influencers will immediately jump ship to the "other side" in an effort to save their own positions and retain their influence in the new order. Some will go quiet and lay low till the dust settles and then pretend like they were always part of this backlash. And some of the most especially blind and narcissistic will double, triple, and quadruple down all the shit that made people hate them, and assume that this will allow them to finally ascend to full political power...only to be hilariously humiliated when their personal political vehicles net zero support at the ballot box.
This is the story.....of how the religious right took over much of media backed by a right wing government back in the 1980s until society finally got sick of that shit in the 1990s. And then again in the early 2000s. Also when the left wing version of this happened in the early-mid 1990s and early-mid 2010s.
