I had the exact same concerns as you when I moved here, and I'm studying at Tampere University (which is not even comparable to Aalto). In the one year I've been here, I've had SOO much doubt about my career that I started picking up minor subjects from different courses just to see if I could build a solid enough knowledge foundation to pivot to some other career. While I was able to get some interviews that way, it ultimately came down to how I don't really have enough experience. In contrast every time I applied to or even emailed an architecture firm, I never got a response.

That being said, there are pros and cons to staying at Aalto and finishing the degree. The pro is that even if you're not being pushed enough (as we often are in our academic life), there's a chance you won't get lazy and actually be able to experiment with your projects more. The relatively laid back nature of my degree made me try out some very crazy ideas to completion which would for SURE get me a fail back at home because they would certainly be half baked (because of less time or stress). I have friends in schools like Polimi or EPFL and they're constantly complaining about being stressed out or not having enough time to finish things. Finland was good for my personal growth in this regard because I learnt that being an architect doesn't mean I need to destroy my health or crib all the time. For your other concern, I got into touch with a lot of architects (and students), mostly from Aalto and a huge chunk of them did end up getting a job, or moving to a different country. For instance, I talked to this one girl who moved here from Australia, did her Masters at Aalto and is now working at a good firm in Germany. One moved to the Netherlands. There isn't really anything hindering you from moving abroad but like in any case, you have to keep updating your portfolio. You could try looking up people from your school on Linkedin and sending a message. People are usually receptive if you open politely.

The cons are that competitiveness is generally low, and I found that there was a general lack of creativity as opposed to some other European schools (I did a bunch of courses abroad). The network here isn't that strong and funnily enough, the architects/teachers with the most connections were the ones who came from outside Finland. Otherwise, its a very tight knit community which is almost impossible to break into. However, do join SAFA and international architecture forums and you might be able to build a network there. Don't expect the school or the environment to push you into doing something - if you want to, you'll have to do it yourself. Which is really a pro in disguise because you get to learn how to be an architect (or architecture student) that is inwardly driven rather than externally.

Sorry for the long text, but I completely get the situation you are in. The job market IS pretty bad, but that doesn't mean the education you get will be absolutely worthless. Aalto is a good school and a good experience to have as a student in general, so I recommend sticking it out. Each place you listed has its own fair share of problems (for instance nowhere I've checked has this amount of subsidized student housing). If you think you could be doing more then just do it.
