The word Punk by itself isn't oftenly used in that context but when applied to genres, yeah it most certainly refers to that. Maybe I was too specific but extreme inequality is almost always a part of it

If you want to expand on your view of it tho, feel free

Probably would. the Punk in Cyberpunk refers to dystopian living conditions because of massive wealth inequalities producing both a class of highly opulent mega-wealthy people and a progressively decaying poor class whose lives are continuously intruded on by those in the wealthy class

A good future would be just a Cyber future
