Why do people discriminate against different branches?

As we all know , engineering is a really broad field . Obviously there are some sought after branches due to some reasons , they are CSE (computer science engineering) , Electronics and communication , mechanical ... But I see peopel who didn't get into desired college or desired stream or people in general talk about streams like BioTech as if they are inherently bad. Its ok if someone doesn't want to pursue such fields but at least have respect if they are more research based / have less money then don't talk as if it is end of the world . People say as if aspirants just get marks . percentile rank and then college the n course and then x LPA package and then call it success story . No hate to those who give their time into getting into a good college they deserve the rewards but people just simplify it into marks , college branch and package and sometimes UPSC . I have seen Vedantu JEE Math do this so I just skip his videos and stop watching shorts ( I am reducing the time for them recently).
