People of Eastern Europe (former communist countries) have difficulties adjusting to capitalism, mainly because of the lack of absolute social criteria.
Life in socialism is similar to life in military barracks: gray, boring, and void of any sense at all. But, life in capitalism is more like life in madhouses: colorful, hysteric, hyperactive, also void of any sense at all.
We, children born and raised in so-called Socialist systems, don’t feel at ease when we have to utter new religious greetings, like “Marry Christmas”, “Happy Easter”, etc. If feel like cursing, against your upbringing.
