In those society, most people are more poor than we are. So what you think are the poors are not. To be poor means there is such a difference in lifestyle from the majority of people in your country that you can't afford the basic things that they can. What is a basic things change from place to place. So what's poor in Africa or China is way more miserable that you think it is. And those persons, instead of being excluded like in our society, are either cast slaves (india), dead (africa) or in camps/prison (china). You don't see no cash affecting them because there is no opportunity for them to be.
