I don't think that egoism is bad. But the problem the way I see it today, is people falling into a fantasy world. They have no tools to deal with the real world. Then what hapens is a big disparity between peoples skills and understanding and how the world actually works. They become like big children - narcisists who want "But I deserve this and that, others don't, buhuhu" the snowflake crybaby culture we are seeing that started with millennialls. Everyone want's to be successfull, but no one wants to do any god damn work.
