I’ve discerned the primary underlying motives:
1. Capitalistic narcissism: The absolute conviction that one deserves the very best things in life because one is paying X dollars for the privilege. Hence, lily-white neighborhoods, prep schools, and an obsession with the ivy league.
2. Pacifistic psychopathy: The certainty that there is never any justification for conflict in life, guaranteeing one always chooses the easiest way out of a situation unless this interferes with the prime directive, in which case one escalates until either the prime directive is satisfied or continuing the conflict is seen to cost more nice things than one will obtain. These exceptions are what’s colloquially known as “being a Karen”.
3. Tactical postmodernism: The ideology that no propositional statement is true, except when this will cause personal conflicts by offending nearby psychopaths (e.g. race does not exist unless one is affirming Black Lives Matter under duress) or interfere with the prime directive (e.g. IQ does not exist but one’s child objectively deserves to be in the gifted program). The former exception is colloquially known as “cucking” and the latter is simply liberal Machiavellianism (which rightists mistake for hypocrisy without self-awareness).
These values are necessary for being the most socially competitive phenotype in the game of status striving among neurotypicals, where the game is defined by the maintenance of SWPL pretense. The upper class, in contrast, are strategically scornful of competition because this aids them in suppressing social mobility–they inherited their status, by definition, and are usually less fit to compete for it.
