> but I find it hard to believe any of these were more important deterrents to the emigration of your peers than our capricious, byzantine, and dehumanizing immigration system.
On average, it is easier for Australians to immigrate to the US than for people of most other countries, largely due to the special E-3 visa which the US has for Australians only.
I know several Australians who have moved to the US, mostly on E-3s and L-1s, and for university-educated professionals, the immigration process itself usually isn't a big issue. The question of whether you want to do it, whether it is the right thing for you and your family, generally looms much larger than visas.
No doubt US immigration can sometimes subject the unlucky to bureaucratic stuff-ups, the capricious application of arcane, unfair and incomprehensible rules – but on average Australians are less on the receiving end of that than most other nationalities – and Australia's immigration department is just as capable of that as the US is. An ex-colleague of mine has a Master's degree in IT, many years experience working in New York's financial sector, fluent in both English and Spanish (he's Puerto Rican), came to Australia on a temporary work visa, wanted to stay here for good, tried to switch to a permanent resident visa – he eventually succeeded, but Australian immigration put him on a very stressful "how can I find enough points?" run-around - when I'm thinking "why are we making someone like this jump through all these hoops? isn't he the kind of high value immigrant a country should be laying out the welcome mat for?"
