Bolivian Ambassador to Iran Jorge Rodolfo Miranda Luizaga blasted the US laws and policies for promoting social injustice in the country, and said Washington which claims to be an advocate of democracy and human rights suffers from acute problems in its society.\"The question is that why a country which claims to be democratic has second-class and third-class citizens,\" Miranda Luizaga told FNA on Sunday. He referred to the social problems that the US is now entangled in, and said there are a large number of people in the US who eat the leftover of the other people and its young people are hopeless about their future. Americans who are tired of their government policies have now initiated the \"Occupy\" movement, which began seven weeks ago in lower Manhattan to decry corporate influence on government and wealth inequality. It has spread to cities large and small across the US and around the world. Demonstrators have spent weeks camped out in parks, while Police crack down on them at every opportunity that they find. And despite its allegations about democracy and human rights, the US is exercising heavy-handed police tactics against its own people.
