The best way to address it is to restrict immigration, so that the demand isn't there in the first place.

For example the USA could end its refugee intake program (which Biden has increased by 50,000/year to 62,500) - which alone will bring in a Wyoming's worth of people over the next 9 years.

Secondly to limit immigration only to other highly developed countries: https://en.wikipedia.org/wiki/List_of_countries_by_Human_Dev... And to persecute and physically prevent all unauthorised arrivals.
