@lacybarry I guess there are several posible explanations:
#fake modesty to avoid be asked to care for the world or others "I am just surviving, so what can I do? I can't change anything myself!...I am hardly living". In that way they avoid people asking them for help in the future.
The #System appreciates attitudes of #self #punishment which can be only words or more than words because is a sign of obedience, low self stem or looking humble is important to keep everyone far from their real power and the willingness to organise with others.
#lazy to think and not really needing others due to their privileges, or having this fantasy that they do #all by themselves, forgetting that even their farts would not be possible without a net of people doing all kind of works, activities or being peaceful so there is some order that allows they to go to grocery shop!
#selfishness because they don't really feel something must change as current situation is comfortable enough for them. So they don't really mean their Apocalipsis like ways of thinking, if they did they minimum would be making preparations for it. So eve they can be climate change activists they don't really believe on that as they don't change any behaviour or cut any consumerism apart from poses.
Being #nihilistic uses less brain resources or is more adequate to people refusing to use their thinking devices since they are young... putting your mind to #think implies doing this on their own and organise with other to change all what they diagnose from their sofa as #hopeless and horrible...
Etc.
