In other words, their existence as part of the system is perceived as miserable as - if not more so - than being outside of it. So why bother trying?
There's very little to no return on investment for their efforts in improving themselves (or being part of the system).
If due to pressing economic circumstances they were forced to work, they would not be any less miserable, perhaps more so.
Glad people like Ronnie James Dio didn't wimp out at their dreams because they weren't tall. But how many Ronnie James Dio's have we not had a chance to enjoy because they thought less of themselves? I hate it.
I don't get anything out of having sex with women I don't like and I generally don't find women to be likeable. Just like most guys I have been looking for love in my 20s just to find out that no such thing exists beyond a mother's love for her children. I look above average and dress above average these days and get a fair amount of unwanted female attention as they apparently love my facial expression of seething contempt for most people.
I fully respect that you have figured this out (because you're absolutely not wrong), but have you ever considered trying to become a top-tier male? Like, throw in a serious year or two of hard work, weightlifting, social skills improvement, cooking, grooming, study, wardrobe, etc etc, to see how the other side lives?
It's not "easy", but now I'm just wondering... since you've figured out that modern society has nothing to offer such men, which most men will NEVER truly understand, why not become the opposite?
