That's usually an argument made by alt-right white nationalists and neonazis though. Western ethnic standards of living and standards for foids can be adjusted when going back because it is a simple principle of taking what you can get or starving.
The main issue is that nobody in the ethnic country will accept you as one of them, perpetually seeing you as a western born confused ethnic male that somehow thinks they are better than others even if this isn't true and you act humbly.
Again I think it's just more of a quesiton if people in your ancestral lands will accept you. It's like with making friends: you can jestermaxx all you want, but at the end of the day it is up to the people you are jestermaxxing to that decide whether they'll accept you tagging along in their company or whether they'll mock you and ditch you when a better opportunity for amusement arises.
If adapting to ancestral lands conditions was the only issue for western ethnic males, it could be more easily overcome. What is difficult is that no matter how you act, as a western born ethnic male you cannot force pople in your ancestral lands to change their perception of you as a whitewashed perpetual outsider.
