Yeah. It is much harder now than it used to be. I know a couple of people who came from the US ~15 to 10 years ago and they had it easy. It was still a nightmare with banks that don’t want to deal with US citizens, though.
As Americans, getting a long-term visa or residency card is not too hard, provided you have a good job. It’s getting the job that’s become more difficult. For other nationalities, it can range from very easy to very hard.
Yeah it depends on which countries you're interested in. Netherlands, Ireland, and the Scandinavian ones are on the easier side as they don't require language fluency to get (dev) jobs, and their languages aren't too hard to learn either.
