Here is a good critique of US mass immigration which is completely applicable to Australia, since the situations and policies of racial replacement are the same. The “justification” given in both countries is that locals will not do the work that immigrants are only too willing to do. Locals are thus lazy and deserve their fate of replacement, the narrative of mass immigration goes.
But, this is not so: “It is distressing to constantly hear that tens of millions of Americans are too lazy to work or too incompetent to hire. Even more troubling is the argument that the solution to this problem is to bring in tens of millions more foreign workers. The reality is that many US employers simply refuse to recruit, train, and retain available and willing Americans. Too many businesses have become reliant on cheaper, unprotected, more compliant foreign workers.”
