I feel like, in Romania, there is a general expectation that you have to financially support your parents once they retire. I've heard from many people around me that they "send money back home". This could mean to parents in other cities, or even in the same place. Usually, state pensions (for which we pay 25% of our salary while we work) are only a fraction of your last salary. If you had a low wage to begin with, your pension won't be enough to survive comfortably.
My mother (57) handles most of the costs that my grandmother (75) has. Things like apartment ownership costs, groceries, etc. Fortunately, for me, I know I won't really have to, since my mother has taken care of her retirement, by saving and investing.
How is the culture/situation in your country?
