All Richs should help the poor

In this world currently, we've people with many and little quantity of money where it generates a social inequality in most societies of countries in the world.
However, in some cases, somebody try to help others. I believe that a rich (like a millionaire and billionaire) are truly rich peoples because they have the habit of helping people who don't have or who are in need of money. In some cases, those peoples have an institution or philanthropic ways that help others with sharing health, foods, education and new opportunity that have a possibility to get with many money and improve more your life.
