If I´m not mistaken, Finland has free healthcare, education and generous welfare system (that you said you benefited from, as you should), all of these should be taken into account when making comparisons, since they factor in the taxes companies have to pay for hiring people.
That said, it still seems a bit low for Finland, but ok for a recent graduate.
Other sources aren't nearly as helpful, but they put me somewhere in the middle of all people (or something).
I'm sure some people earn more, especially closer to Helsinki, but currently I'm content with my earnings.
So don't be surprised we worry about money.
I was working at a video game publisher at the time and we tried to take advantage of it, being an American company but with roots in Japan, but there was some cultural and communication issues that helped lead to products that didn't sell too great and negated all benefits of cheaper development in the first place.
I wouldn't be surprised if many of those companies are still struggling today.
Furthermore, having money to buy unnecessary stuff for your hobbies is not the metric to go by. The more important metric is about what you're able to save. Important questions are:
* Are you saving enough money to ensure a comfortable retirement?
* Are you saving enough money to buy your children (assuming you have/will have them) a decent education?
* Are you saving enough money to cover medical expenses later in life?
* Are you able to set aside an emergency fund?
If the answer to any of those questions is "no", then you should probably be concerned.
