this has always been a place for people who want to work hard, whether immigrant or native, just ask someone like Aaron. I truly believe, from experience and observation, that success, especially academically, is available to anyone willing to work hard enough for it. I have plenty of friends who have worked and gone to school full time, who are neither rich nor sponsored. You can still go to school for around 10 Gs and the govt pays some of it and you can get loans(which in the long run turn out to be cheaper than european tax rates). And no way in hell are european city as welcoming as american ones, americans celebrate and like diversity. europeans are suspicious and wary of it, i d describe it as an american naivety because they are so remote from the old world, the proof the only immigrants that are 'feeling' it in the US so to speak are mexicans.
And finally to the doctor whos driving a cabbie, 2 possibilities, either he cant cut it here or hes content driving his cab(which reinforces that this is a good place to be). Hard work still pays off here, expecting handouts not so much.
