Happiness & Who needs happiness?

A soldier on a vehicle to a war zone might say to another soldier, when the war is over we can go home and eat a little more and sleep a little more. There is hope that he returns back to the land which he is serving. When soldiers are protecting the borders and fighting we are doing our part in the country in varied fashions. 400 years of foreign rule have changed the country so much that we forget that the freedom fighters fasted, they went to jails so that we are not dependent on some souls. Today, we forget everything, our soul purpose is our happiness which has driven the goal oriented country wanting freedom to selfish self centered souls who only look at their happiness and not at the progress of the country. This country has the rich, the poor and the middle class, the disparity between the rich, poor and middle class is so high because everyone is on their own. A kid is ready to spend 1000 bucks on a beer but not ready to give to charity because he feels his enjoyment is more important than someones daily meals. I am surprised people still live in slums, have 1 meal, die without crossing 1 year of age in this country and there are elderly who are not taken care properly by their kids. There are places which have no access to medicine, proper living facilities but it doesn't bother many. Why this happens? This happens with the fundamental flaw that we are taught to be happy and not to make someone else happy. Kudos our education needs to change to make 5 people happy can 1 person sacrifice his happiness?
