Here is an interesting debate, as Central bank governor Philip Lowe has said that high immigration has contributed to the country’s weak wages growth. As I see it, mass immigration is loved by the elites precisely because it does decrease wages, for increased supply of labour, and a reserve army of the unemployed, less drive for wage increases. The neo-classical ideological economists, the equivalent of wizards of old will bs to deny this, but simple logic shows otherwise. Just imagine an economy at time T1 which has X number jobs. Even if migrants did create some jobs, as you increase the numbers, say to billions, the increase even hypothetically drops and disabilities rise. Eventually people are falling over each other, suffocating on immigration.
