they'll be interviewing someone about the Housing Crisis ™, anyone, some random punter and the random punter will say "it's the immigrants, all the immigrants coming over, there aren't enough houses as it is, we're an island, we're full, the immigrants, houses"

What do the random punters think are happening in this scenario? That someone is just coming over with 300k and buying up all the houses and pushing the prices up? Or with 100k and getting a Mortgage? Or do they think that immigrants are getting all the social housing, jumping to the top and then they've considered the possible and complicated knock on effect that this might have on prices?

What are they thinking?
