You seem to have a negative attitude to the third world but if I was living in Bangladesh or parts of the Middle East ruled by psychopathic dictators I would also have a go getting here--at the land of milk and honey.
Until about 15 years ago secondary schools on the outer fringes of Melbourne were shit-hole war-zones between staff, parents and kids.
Kids in those schools learnt nothing and knew they would follow their parents on welfare so they didn't give a shit about studying.
In the past 15 years thanks to Asian kids from India, Cambodia and Bangladesh as well a Chinese and Vietnamese those schools are going really well and achieving great scores.
If it was up to people like you this country would become the biggest first world shit-hole banana republic ever in the history of the planet.
Thanks to those great smart kids and their parents who want then to study, they will one day fix your haemmaroids and feed you in a nursing home.
Those migrants have given our nation a chance as the Anglo-Saxons in a lot of outer suburbs are no better than their shitty white trash Pommy convict ancestors.
