Sikora, if you had the chance for Holland or Belgium, choose Holland. It's a real country, whereas Begium is not.
Actually, the Netherlands is a real country, and strictly speaking, Holland is a region of the Netherlands.
True, but that's just pedantic.
I certainly fall into the economic migrant category. I moved away first to get my research done, and then stayed abroad for economic reasons. The job market was thinner than usual when I graduated, and there were jobs in Europe. At the time, there were more jobs in the US than in Canada, where I grew up, and I fully expected to end up there. I did live in the Mid-Atlantic area for a while, but it didn't last.
I've now been 'away' for well over a decade, and I've found that the home country has changed so much that I can barely consider myself part of it either. So I was born in Canada, and the socialisation I received was a major influence I'll never shed nor want to shed, but I've really moved on. Every place has its good and bad points, and it's best to simply look at the mix and choose the place that best suits your personality. I wouldn't go back to the region of Canada I grew up in. But other areas, if the price is right, might lure me back.
I frequently get asked by my students whether it would be better to settle in Canada or the US. I tell them that if they want a society that places more emphasis on security and is less individualistic, then they should choose Canada and be prepared to pay higher taxes. If they want more individual opportunity, and are willing to take higher risks, then they should choose the US, and perhaps get to pay lower taxes (before health insurance premiums).
