Do you have anything to back that statement up? 
YEAH..god damned tens of millions of american in tent cities, welfare, medicaid, trailer parks, homeless, shelters yadda yadda. Sad part about it...there is no reason for it. America is not like China or India with over a BILLION people each, it is not devoid of resources, it has good water supply practically everywhere, schools, churches, libraries, infrastructure, industries etc are everywhere. You lack for nothing yet america has created a horrendous disparity between those who have little who work to make sure that the few who are wealthy stay that way if not become more so.
Don't act like you are not aware of the situation in america. One thing that people see going to america is the extreme poverty in many cities..and it is always a shocker as we are always told of the grandness of america and that everyone is doing well...yeah right!!!!! Europe is not perfect adn neither is China, Japan etc, but at least these places do not do as america does and pretend that poverty does not exist or that those who are poor are so because they are lazy or don't want to work.
