This is how it should be. The rate of immigration should be proportional to the investment in housing, infrastructure, and gov services. Importing people without increasing investment or efficiency just damages the quality of life and cost of living for the existing population... but it enriches our corporate dictators so is standard across the developed world.
This fascist fuck won't do it though. He's just a criminal trying to con idiots and racists, the same as every right wing politician on Earth.
