I was just thinking the same thing about the Netherlands in particular. Lots of English speaking jobs for highly skilled people. Look around the Hague & Amsterdam. Lots of nice places to live within a commutable distance. From what I noticed Americans seem to love it here and I get the impression that the Dutch quite like Americans. Just give it a try before going all the way back to the US. You can then still enjoy long weekends in France as the train journey to Paris from Rotterdam is only two hours. Good luck.
