describe the life, as lived by the ragpickers of Seemapuri. why is Seemapuri on the periphery of delhi yet miles away from it?

The ragpickers led a life that was devoid of all basic facilities. There was no sewage system, drainage structures or facilities like running water. Many of them were immigrants from Bangladesh and they often settled wherever they could find some food. Such was the condition that they had grown accustomed to the situation where they had ration cards to get food but lived without a proper identity and without permits. Therewas such scarcity of food that to sleep without a rumbling stomach was an aim in their day-to-day lives. The huts were made of mud, roof tins and tarpaulins. Children walked barefoot as they couldn't afford shoes. Even if someone had got a pair, they were surely rugged, used, discarded ones, often mismatched and sometimes with holes. But to own shoes, even as the ones mentioned before, was a dream come true. They lived in utter poverty devoid of education along with other basic rights. With the means to move forward in life unavailable to them and the harsh struggle they had to carry on to survive everyday, they usually turned into ragpickers. To them garbage was gold, not only because they sometimes found some rupee notes in there but because ragpickingthrough thegarbage helped them survive and earn a livelihood.

Delhi is a place which is well developed both socially and economically but Seemapuri being Quite near Delhi still lacks various facilities and people living in Seemapuri face several problems. It is nothing like Delhi. So I think, may be the author wants to point out that though being near Delhi, the status of Seemapuri is like a rural area which is very far away from the city as well as unnoticed by the politicians or the government.
