In Australia something similar happened with legal immigration going wild. Obviously there are issues of regulations and NIMBYsm which are far worst than in the US but also because construction unions opposed visas for construction workers, so there is a shortage while all kind of people with unnecessary jobs streamed into the country. The squeeze is from both sides of the political spectrum, asset holding class benefit from it financially and the left benefit from it electoraly by creating poverty and state dependency. No wonder extreme political groups from both ends of the political sides are gaining traction. Those politician betrayed the middle class and working class.
