No one is helping the Third world countries

The developed or the stronger countries consider them nothing in front of them.
 Even the decisions about the nations of all the countries made in the united nations taken by the developed countries.
And the developing or so called the third world countries has no right to speak against their decisions.
The condition of the people in these third world countries is very miserable, even they are living a life of insects.
But there is no one who can understand these people or can help them to come out of this condition.
