The term elite is pretty nebulous. When the right uses it, they generally mean people who are experts in their field having dedicated their lives to studying something, have higher educations, are part of prestigious alumni groups etc. Somehow, the mega rich folks born with a silver spoon and who shits in golden toilets, dont register as elites. I guess by virtue of being a conservative, it must be impossible to be an elite in the MAGA mind. In any case, its just a buzz word they throw around and try to give a negative connotation to. They want their base to be distrustful of people who have dedicated their lives to science or statesmanship and instead favor outside disrupters to come in and tear down established institutions and traditions based on facts, evidence, and experience.
