Feel bad for the professors

I have this one specific class that at least a couple are always missing from consistently, and those who attend don’t even bother looking or acknowledging the professor. I understand it’s none of my business to care about what other students do during class but if you are paying for classes then pay attention no? It pains me to see the professor teach about the topics during class and very few people are actually pay attention. They put in effort to teach and prepare for the class and only a few are paying attention. Do yall have any experiences similar to mine? Or do I just care too much?
