General Discussion

verbalises the seething resentment that a lot of people of low skills and intelligence feel towards their life and the rest of the world.

They feel that others are holding them back. Workmates, family, dem politicians, all holding them back from what they promised themselves their adult life would be like.

The concept of 'doing something about it' or accepting their current state is beyond them.
