According to the position of leftish thinkers, this principle presupposes the government’s intrusion into people’s life – if there is no such intrusion, the equality isn’t supported. In their opinion, this concept means that every person should have equal possibility irrespective of all the other aspects of his and others’ lives. He may come from any kind of family, receive any education, but still be eligible for the same things that a person who came from a completely different background and was brought up in a completely different way is.
For Each chapter I have told two or three books or sources due to few reasons. Since each chapter has many topics and one particular source won’t have all the topics covered or even if they are covered then they won’t be very good. So out of the sources mentioned you can figure out which one explain which topic in best way and read from it .Don’t try to read one topic from multiple resources until they have something extra or you lack clarity. Other reason for telling more resources is you might not have all of them; in that case you can refer to other resources .
