Anon,

  i myself lived in australia for a long time, outside you dont' see much of a racism ..but if you work in govt or large corporation its highly racist country, if you want to progressed ahead you are limited by color/race and religion, if you work on resturant/cab etc you wont' feel any racism until u end up in QLD or Western Australia.

I have seen many of my friend left australia even they were citizen of australia for the career n better life. I travelled around USA and seen my self , visited my friends and saw how happy they are compare to here, that motivated me to make a move as well.
secondly australia housing price is overly- inflated (artificiallY)  owning a house is almost impossible unless u give up everything.
median house price runs around 550 - 600 k that is like 2 brm house with 300sqm land n almost 45 minutes from city centre.

australia is one of the highest taxed nation + very expensive place to live. yeah its little more clean, more greener, open areas..playground etc but then your savings is 0 ..even rent is way to expensive unless you decide to rent 2 bedroom apartment and share among 8-10 ppl as many of them do here now.

If you looking to progress ahead on merit basis n have more comfortable life USA is the best place to be. i 've travelled quite a lot of places and i feel USA is best for non- white people.

but if you work on hospitality/cab/cleaner Australlia pays well..the earning between highly educated intellectual and non educated profession is very similar. so its upto you

every place have pros and cons but i prefer USA and i myself looking for an opportunity in USA ..and will move if i get any.,

i hope this helps.
