You keep talking about herd mentality - "our" society, "this huge pack of people" etc. Who are these people? I don't particularly feel like you and I are associated in any way. "We" aren't doing anything to anybody. If you feel like you are contributing to an unethical enterprise, and you don't feel good about that, then stop doing it.
Likewise, if you feel like you aren't producing value and doing the hard work and learning anymore, then this is a problem that you must fix. I'm over here producing value and doing hard work and learning. I can't speak as to whether what you're doing is worth anything - that's your problem.
