Developing countries tend to be corrupt business owners (corporatism) and wealth concentration that only helps those already with too much power over the government (the same corrupt business owners mentioned before). Many believe that the best way to solve the problems would be to take those people's money and distribute to the poor, instead of fixing the political system and punishing those who are influencing the government in their favor.
Since many blame the rich for their own disgrace, they truly believe that taking money from the rich is morally correct. This belief is still common in most left wing parties of Latin America. This way of thinking has been spreading in North America as well.
