just because we need to feel things are just getting better

That's 100% true. But usually the people who want to return to BG are those who have been in other countries for many years and have totally lost touch with the reality in the country. I really feel sorry for them for the absolutely wrong choice they will make. Although, BG is a good country for people who retire in foreign countries and come to live here with the high pensions from there. It is not a good place to live in any other case.
Besides, one wants to see some progress in general life, really, but in BG such a thing has not happened since... so many years. And the lack of any progress at all ever can even make people feel good because they haven't seen anything good and expect nothing either. But for people who have ever seen something better, I don't know how this situation will affect them. Anyway, to each their own judgement, right?
