So “you were born somewhere ‘unlucky’, that’s how it goes, sucks to be you”.

Is that really your take?

Naïve take. We live in a global neoliberal economy, our standards of living are the direct result of introducing scarcity and other forms of exploitation elsewhere while keeping domestic populations largely unaware of how unfair their position is. There is no ethical basis to simply "focus on ourselves" here. We must do the exact opposite.
