I think Syngirl hits the nail on the head--will it be enjoyable?
It's clearly doable as many here attest. But will it be enjoyable for an expat with even modest American standards is another thing.
Even if you're from NYC, cheap apartments are unusually small and low quality here in comparison. Prices of most things are as much or more than in the US for much lower quality.
Expats traditionally came here for a better life than they could have in the US on little money. That's gone. Now working here on a local salary just means living a lower quality of life than you could with a similar job at home.
I get the part about the experience and adventure. And that's the only reason to come now for a young person with no money. For those making foreign currency salaries it's still a relative bargain, mostly in housing savings and cheaper high end restaurants. But I think it's just hard for some of us to think it would be very enjoyable for an expat to live here now on a local salary.
