Oh no I can't stand the scalping concept. I get some people might be desperate for the money if you already own one and can now get 2-3 more for it than what you paid. But to deliberately do it is shady.
I'm in England. Looking to move out though! Part of my fighting to stay in involves moving to a mainland Europe country if I can. I just love the idea of being able to move around without borders.
I can't say I blame you. I'm English aswell btw, so pleased to meet you. (Although my username is GeekishlyGreek, that's because Greece is actually where I live, and have been doing so for nearly 10 years now, so is very much where I consider home). -My spouse is Greek, and our daughter was born here, so this is where we will be staying for the rest of our lives). So from someone who has lived what you are hoping to do, one thing that may give you solace, is that the world view in the rest of Europe is very very different in real life to what our British papers and even TV outlets try to have us all believe. (I'm fortunate in the sense that I get to see what's going on first-hand from both sides of the pond).
The good news is that while every country has always had a variety of issues with decisions that get made at EU level, it's only Britain that think that Free Movement is the bit they want to completely get rid of. Much of the rest of Europe are actually fighting to keep it, and the sentiment for that amongst the majority of its citizens is actually very strong. The main difference is that for a European, the right to live, work, study, and travel freely between each European country is as normal to us in mainland Europe as it is for a British citizen to travel freely between two British cities. (imagine how weird it would seem if one day somebody suggested that we're going to ban people from traveling freely between, say, Yorkshire and Manchester without applying for a visa, or from any district to another for that matter). -Not only would such a suggestion seem so bizarre that no-one would ever suggest such a thing in the first place, but the amount of citizens that would be negatively affected by such a restriction would mean that they would never let their leaders get away with trying to impose such a thing. (...imagine you live in one city but work in another, or you are married to someone who was born in a different city, or your university, school, or place of work was in a different district to the one you currently reside in, what mayhem that would cause if you were suddenly confined to only being allowed in the one where your house is).
So this should give you some idea of how it is between EU countries and its citizens. (and more importantly, how and why the mindset is completely different from both sides of the pond). So both viewpoints are completely understandable as to how everyone ended up with the differing perspectives that they now have. (The reason our media tell it they way they do though, is because they are looking at the world through the way it seems if you've only ever seen it from the way it looks through their eyes). But the reality is that you're nowhere near as alone as it might feel sometimes. If it's any consolation, life outside of the UK is something that I do not ever regret. So if it's something you feel passionately about, then trust your instincts! 10 years on, and I have never looked back!
