Why media see Mandela as a saint but Chavez as a sinner

There has been limited social and economic change in South Africa since the fall of apartheid. Nelson Mandela helped defeat apartheid but he did not bring economic transformation for the mass of people living in poverty.
In terms of the media and political lexicon it is interesting to compare the attitude to the death of Mandela with that of Hugo Chavez, who did bring economic transformation to Venezuela. Whilst Mandela is viewed as a saint, Chavez remains a sinner - these different attitudes say much about the capitalist values that underpin many of the recent Mandela tributes
