Thanks for adding some reality into my perspective, moving to Sweden is something that is always in the back of my mind :) I could gush about it all day haha I really like the way Sweden has it's State organized, I do think that not only is it like you said, better overall(sorry my fellow patriots), but also better equipped to handle political changes as well.
I think that is a big upside to the system. A new party that adresseses new issues can get in and change the political landscape. It looks like we'll get a feminist party in parliament in the fall for example, and the pirate party got in to the European parliament. And compared to the rest of Europe Sweden is doing fine. We have our problems but so does every country. I wouldn't discourage you from moving here. Several of my teachers are from other countries and I think they all came here knowing no Swedish at all. It is doable, but I wouldn't say it's not difficult. One thing you could do if you're not already done with it is study here to get a feel for how living in Sweden is. Unfortunately non-Europeans have to pay for it these days so it's not as simple/worth it as it used to be. But I'm not unaware that we have a great system here, and I am thankful for it.
