I know what you mean. I've traveled to certain very rural, village-type of locales in Africa and other places, where water is so scarce, it is a privilege if you don't have to venture too far to obtain a bucket... Some people in the US may not know what a luxury it is to just twist the knob or lift the handle near your faucet and get a rush of clean running water.
Or not have to worry about holding in your shit because you don't want to waste the bucket of water needed to flush it.
The difference I see between the US and other much poorer nations, however, is very significant. I was told by a young woman in Ghana, that in the Africa she knows, people rarely go hungry because there is always someone down the road who will give you a meal. There seems to be a sense of community and goodwill there that perhaps gets lost in societies that pride themselves on development and industrialization.
Likewise, in the countryside of Ghana, I didn't see any homelessness. It appears that there will always be someone who will give you a square of their bare floor to sleep on. They may ask you to do their laundry in exchange or comb their hair every night and rub their back. Some kind of agreement or small favor.
It's just so ironic, that in the US, this great superpower, with all its government programs and social welfare institutions, people may not be able to obtain a meal. It makes me wonder if the price of industrialization and urban sophistication is anonymity. People in the cities get cut off from one another, we lose the sense of community welfare. We're able to walk past someone sitting in the street, shaking an empty can because it's not our problem. We don't know him or her.
I guess what I mean to say is that in the US, if you are hungry, you may not feel comfortable ringing your neighbor's door and asking for a favor. It would be embarrassing and not the social norm. Whereas in other poorer nations, asking someone in the community for a plate of nice is fine, part of the customs. In other countries, people are more familiar and open to depending on each other, not on the government.
