because people are need someone to blame. they can't blame themselves.
hence why you have 30+ year old children who blame 'society' for their failings, or their parents, or a ANYONE but themselves.
and if you suggest hey... maybe you can learn and work and fix these things... they don't say 'oh yeah i will do that'.
they go 'fuck you YOU HAVE NO EMAPTHY AND ARE A HORRIBLE PERSON'.
because... their entire identity and meaning in life is being a irresponsible piece of shit person who blames everyone else.
