From Das Kapital, I know that rsv = s/v = (Value Added - Wages) / Wages. Consider calculating the avg. rsv of a real country, the US for example. Statistics evolves from Marx's time and I don't know what data to look for. Someone told me that I can't directly use GDP for Value Added, and I don't know whether there exists an index for Wages. Maybe GNI? New to modern economic statistics.
