I moved from one of the shittiest Eastern countries to the "relatively wealthy Western Europe". And it was 2018 where I "just jumped on airplane".
How am I detached from reality when live in it?

Outside.
It's not 1900 where you can just jump on a boat. Comments like the one you quoted just seem completely divorced from reality.
