I prefer Romania for now because I earn well enough, and things are still cheap compared to Western Europe. The only reason I'd move is if some far right party got into power or to catch more concerts.
Obviously there are exceptions. And some countries, including Germany, are trying to snipe highly educated immigrants, which would of course earn decent wages. But not everybody falls into that category.
Usually people from other countries will have a tougher time on the domestic job market, and there's a good chance your real spending power is less than it was before.
