They mostly feel nostalgic due to the economical and social hell happened to them in 1980-2000. Most of them never recovered from these times and could not adapt to new reality not because of brains washed, but because you cannot simply make it to the top after losing / not having it all. Ask your local homeless guys why they don't buy themselves a house, car and good life. Multiply that by pretty median smartness and hope for "it would fix things if returned" and you get the result.
