I wouldn't agree with the author's sentiment: "The reason why I decided to stay here in the United States, despite a couple of efforts to return to Finland, is because I like it when people smile, laugh, and, yes, even talk to their neighbors." My Swedish neighbours and Swedes in general have been delightful, though I know things may be different in Finland.
I think it's great that places like Sweden exist, and might suit most people, but those who wish to lead lives of high variance with high highs at the cost of potentially ruinous lows should be able to do so as well.
