A more reasonable policy would be to make sure the that doesn't happen. Say by abolishing racist policing, better urban planning, better labor laws, and partly socialized job market.
EDIT: Changed wording, previously incorrectly stated that immigration was natural under these circumstances.
It’s not clear to me that these things are true. Unions and socialized job markets, for example, often exacerbate ghettoization by excluding née entrants from the labor market.
It’s hard to argue with the success story that is the US. Nearly every immigrant group in the US has seen incomes converges with the native population within a few generations. Even today, that’s happening for Hispanic immigrants.
That’s true few other places. Fourth generation Muslims in France, for example, are still often ghettoized.
I don't think runarberg meant that xenophobia is acceptable or proper.
My response may have been a bit touchy since the US is dealing with some pretty big issues right now but I think that the meat of what he said w.r.t. improving quality of life as a way to address increasing xenophobia is spot on and I'm very much of the same mind, when people are trodden on some object upwards and others find other people they can trod on themselves (transitive bullying or some such?) and bringing QoL up across society with good supportive social programs can really help minimize Xenophobia and shift it from a belief embraced by a group that has been sorta-kinda denounced by politicians to something entirely fringe (like neo-nazis and the KKK were in the 90s).
It’s been a while since I’ve read up on the literature of psychological biases, but I don’t think there is a clear case that we have inherit biases towards outgroups. Or at least any experiments that previously have demonstrated such biases have had biases them self. I at least wasn’t ready to accept a theory of outgroup prejudges being ”natural” without resounding evidence from good experiments.
A Marxist might argue that given the previously mentioned conditions (in particular worker alienation) would create an alienated “outgroup” which others (including the working classes) would learn to despise. However this is hardly something that some might call a natural condition. And marxism is far from being an accepted theory of human behavior.
There is an abundance. Check out the literature on adult development. I’m partial to Kegan’s model, but others work.
Here is an accessible article on Kegan’s work:

Kegan might not say that stage 3 folks are inherently biased towards outgroups, but they are certainly defined by their in-group. This can lead to challenging perspectives when dealing with other groups.
E.g. they were asked to rate neutral images as positive or negative, some were primed with images of outgroup person while others with ingroup. The outgroup group would respond more negatively. But there is a problem with this design and they found out that it is not bias towards the outgroup that created the result. Maybe they have experiments that demonstrates (without a bias) that xenophobia is natural in humans, but I doubt it. I want to see some extraordinary evidence before I believe such an extraordinary claim.
Edited the previous comment to reflect this.
