Question

How far has been the idea of heaven of freedom been materialised in mordern world

Answer 1

It is always good to give both sides of the story. So one could talk of the fact that largely the human race is now free from hunger (though yes, about 1 billion possibly still face hunger / malnutrition), free from slavery. However, we can yet not call the modern world a "heaven of freedom". There are large sections on this planet where women do not have the basic rights (Yousufzai Malala would be a good example, how she fought for her right to go to school), where people do not have the freedom to choose their own Government (Saudi Arabia). Recently, terrorist groups such as the ISIS have been putting people in captivity.

So while basic needs may have been fulfilled, there are other forms of deprivations that continue to exist.
