This kind of talk makes me happy to live in an european country where people of all walks of life can meet in every street, every gym and almost every neighborhoods.

Where I can have a chat with somebody without having any idea about their "success" and "class".

I wonder how much the "rat race" mindset correlates with depression, anxiety, cynicism...

I live in a rat race city and this mindset really only exists in the less dense areas. Never met anyone when I lived in the dense part of town who would think twice about speaking with me.
