The fires are horrific; here in Southern Oregon we're getting quite a few refugees.
I think the U.S. could easily absorb more immigrants and refugees.
In my town the problem is that the houses are mostly post-war, built for larger families. Population is actually decreasing (in my city) but their aren't many of the small apartments that people need. Zoning was just altered to allow people to build rental cottages on their property, but that will take time.
