So maybe we won't need to wait for the "decade or two" you mentioned. But for what it's worth, while living there (in Umeå, actually) for half a year I got the feeling that people really do set priorities differently. I'm hoping Swedish society will more or less stay that way. Even if that society is based on "peer-pressured conservative egalitarianism". For I like to know that there's a place I can go when I've had enough of peer-pressured competitive consumerism.
I've lived/worked in many cities/counties around Europe and have also lived in Boston, and one thing is for sure, there is no one perfect country – I don't take all of what the video says at face value. We (humans) think it is always greener on the other side, but it is rarely the case. Regardless, some of things that work, work very well, and are big problem solvers for citizens. See the case of public healthcare all around Europe.
Some people have already mentioned some of the downsides to Sweden (weather, job permits, etc), but to say that what Stockholm (and by extension Sweden) has achieved is "based in peer-pressured conservative egalitarianism" is being short sighted – the same could be said of Russia and other eastern European countries, and yet here is Sweden. What has made this possible are the people, who have made it pretty clear what their priorities as a society are on healthcare, environment, energy, education, etc. This doesn't happen because a country closed their borders (I take it you have a bad view on immigration), and by a stochastic process all this goodness happened. This has happened by design (and yet it is no problem-free, only better).
