How do you define the "elite class"? I personally hate the term "elite" because it seems to have become mostly a pejorative that is synonymous with "liberal" than anything else.
However you define it, I think the perception of the people who consider themselves workers - and not part of the "elite class" - is just as important, if not more so, than "elites'" perception. Let me give you an example. I have a group of clients who own businesses in the home improvement field. Most of them did not go to college, and most worked in the home improvement field in some fashion (selling home improvement products, installing them, or both), or other traditionally blue-collar fields, before starting their current businesses, which each employ dozens of people (either as employees or independent contractors) who work in the office, makes sales calls, or do installations. They have all been very successful with their businesses. They earn anywhere from hundreds of thousands of dollars to millions of dollars per year through their businesses. Most of them make substantially more as business owners than I do as a lawyer.
By any reasonable measure these people are not "working class." They are the business owners who employ the "working class" people. They earn incomes that probably place them in the top 5% or so of Americans; some of them probably in the top 1%. Yet culturally, I can assure you that they very much consider themselves working class, and me, their lawyer, as an "elite" who is not working class. They are mostly or all Trump supporters; some probably very ardent Trump supporters. A couple months ago, one of them said on a call something to the effect of "things are getting bad in this country, man; you lawyers are doing some scary things, and us normal people are just trying to hang on." Mind you that this is a guy who earns millions of dollars a year, lives in probably a $4 million house, and takes 5-6 vacations a year.
To me the point of this example is that "working class" is a cultural identity as much as one that has anything to do with income or whether one is actually a "worker" versus a business owner. Small business owners in the trades or sales or related fields - who as a class tend to be disproportionately conservative, and now MAGA - usually consider themselves to be "normal people" oppressed by the "elites" whether they earn $30k, $150k, or $5 million per year. And they probably consider anyone with an advanced degree - or at least anyone with a liberal arts degree - part of the "elite" whether they're working a low-level job at Google or earning $2 million a year at Skadden Arps. That isn't a perception that has been imposed on them by the "elites" - that is one they have formed and developed on their own, probably influenced to some extent by their media diet.
