Wow, the pension in your nation is very little, it could barely sustain someone for a day, well in my nation these pensions are kinda higher though, some earn up to 40. Dollars in a month that could be able to sustain the older parents for a while.
Yeah, you're very correct It is the upbringing of the child that matters if the child grows up to take care of his or her parents or not, but then the child should be able to support the age parents in any way they could.
