Ofcourse it's hard moving to another country, but what people don't realize is that it is harder now to get ahead in a new country than it was years ago. I moved here in 1966 and the first 5 years were very hard but I'm at a place now that I doubt I would have been had I stayed where I was. My children have also had very good opportunities and have wonderful standards of living. However, I do not envy anyone who emigrates now. The same opportunities are not there in the same number as they were. I would not try to discourage immigrants but would make them aware that they will go backwards in standard of living because they will not , as a rule, obtain the same level in their profession/trade that they enjoy now. They have to start working their way up again. I do have to add that this is a great country and well worth the effort - as long as K Rudd and Co. don't stuff it up.If you think it's hard then it will be.
It's no harder than any person moving to any new country.
