Snobbery is not a personality flaw, but a time firewall for high-efficiency individuals.

The essence of social interaction is value exchange, and time is an irreplaceable absolute currency. When someone shows you “snobbery,” they are actually engaging in extremely rational resource stop-loss. They reject your inefficient connection in order to reserve bandwidth for nodes that can generate leverage effects. Those who are enthusiastic with everyone are usually because their time is worthless, or they urgently need to turn you into a cuttable leek.

The “indifference” you feel is just because your exchange value is lower than the other person's opportunity cost of time. In this market, no one is obligated to buy your subpar assets at a high price just to preserve your self-esteem.
