It isn't on my list of anything to be honest now that I have lived here for a while. I now realize that it's all made of nothing. With large salaries comes a shitty life quality; crappy food, awful health care system, undependable transit, toxic political/cultural environment.
Meanwhile, in Europe or even Canada, skilled workers are welcomed and even though salaries are less, one gets an impeccable quality of life which is the point of working to begin with.
