As an example, I, receiving a good white salary, calculated the deductions to the state funds in recent years and found that with that money I could: pay both grandmothers their current pension, watch the whole family regularly in a private clinic and still postpone for old age. I am one. With one salary.
And in fact - for the treatment of the whole family I pay extra (free of our all familiar) and PFR on the verge of bankruptcy, so the pension is far from guaranteed to me.
