"Lip-service" is probably a good way to put it, since all those issues are also happening in countries without a lot of immigration, but most people don't look too far outside of their own country when considering problems in it. It is easy to look for a simple to understand change, and lay the blame on it, and people like easy answers for things they would rather not have to think about (like economies).

Most of those issues are probably better explained by the trend for jobs, especially higher paying ones, to be more and more concentrated in cities. There has been almost no policy push to realistically address that from anyone, outside of lackluster and temporary measures to encourage jobs in smaller cities.
