Of course. But realistically, no one wants to deal with the inevitability of ageing populations having to either take the bullet and accept they were sold a bunch of lies, or causing the working class to crumble under the collective weight of all who depend on them. Most immigration and pushing for higher birthrates is just that, an admission by politicians they don't want to deal with the problem and passing it onto the next reigning party.

That said, it's nowhere near the sole contributor. Quite a few countries have very low immigrant numbers along with low birthrates and still face soaring house prices. Rampant individualism doesn't help, either.
