In your opinion, are these policies bald attempts at keeping migrants from Asia-Pacific countries out of Australia or is there a deeper-seated historic animosity at play? Culturally, are the psychological scars of Australia's previous status as a British penal colony still manifested in public policy? I don't ask to be incendiary, but because I'm interested in the Second-Order Effects that stick with cultures over time, often in seemingly unrelated ways.
