I do agree that low salary is an issue, but it's improving. On the other hand, it's very hard to compare everything, when you're young, single and healthy, it's a no brainer that you should take your chance in the US. But if you have a family, suddenly are diagnosed with a costly disease of whatever kind, I bet you wish to be in Europe.

So articles that say "you should go west" just applies to their authors, everybody has their own set of parameters to evaluate, and the answer isn't so obvious. I personally have kids and a wife that earns a lot of money. I've done the maths, it's a no brainer for me financially to stay in Europe...
