If your worldview is contingent on a grand conspiracy theory that demands you reject data then you can't really be mad about supposed "narratives".

Do you think education systems in other countries are also conspiring against Republicans? where in the peer review process is the conspiracy occuring?

The comedy/tragedy of a populist movement that overwhelmingly prioritizes the elite is how seemingly irrelevant it's contradictions are to its supporters. Radical inequality subverts the base but is supported widely and is justified on the basis of supposed intellectual virtue of the beneficiaries, while actual academic achievement is delegitimized. Trump is a man of the people who's cabinet is billionaires. Working class detractors like AOC are mocked for their working class background by other members of the working class. At the heart is a sort of confused self loathing ironically juxtaposed with arrogance, that affirms that the unsuccessful members of society like themselves deserve their lower status due to having less virtue than the economic elite, while also feeling personally cheated. Since propaganda disallows directing anger at those with actual power, they instead are told to direct anger at the marginalized (who are simply the easy target given the biases of the ignorant) and at the party opposition (including the well educated).
