You might want to mark this post as OT.

A full-time developer (not equivalent to architect, IMO, with only 5 years experience) with relational database, Perl and C++ experience in Seattle can expect to take home as much as $5000 US dollars a month after taxes and other withholding. Checking my handy USD->Euro conversion chart, that seems to be nearly 3900 Euros a month. If you are being paid substantially less than that, you might consider investigating some other options. :)

Admittedly, comparing salaries across continents can be an apples to oranges scenario, but it might at least give you a ballpark view.

Update: As pointed out by others in this thread, cost of living is a major factor. The average home price in the Seattle area keeps increasing -- I'd guess it is over $450,000 by now (still quite a bit lower than many coastal cities). Personally, I commute an hour to work because a home large enough to accommodate my family (5 kids) within an easy distance is out of my reach financially. Ideally, you'll want to get a telecommuting job that allows you to live somewhere cheap and still earn a decent wage (I once had a job like that but was laid off, sigh.)
