Deep thinking about primary source

My primary source is one of a series three pictures which were posted on a magazine Large. The picture is about a poor homeless man is donating coins to another homeless. The first time I saw it, I didn't get the deep meaning behind this picture itself. Because it is so hard to get only one theme here. The theme can be: People are equal; even poorest people are warm-hearted to help people; or only people in the same class cares each other. However, the small text in the picture reveals its value:"For people who think bigger than they are. It seems clear that to appeal public to treat people equally, do not look down people based on class and social status. But, I am so confused. If the poor donates to the poor means equal. Does it mean unfair status if the rich give money to homeless and the rich are arrogant? If the picture shows a poor man is helping a rich man, for instance, when a man is injured by a car accident and a passing by homeless donates blood immediately so that the rich can be alive. Then we can say:"For people who think bigger then they are." which means for love, for human nature, we all are equal. Nevertheless, come back to the original picture, I get another meaning: for the rich, donation is "Charity", but for the poor, it is "Love". A lot of impressive stories about poor people help others occur when catastrophic Wenchuan Earthquake happened in Sichuan Province, China in 2008. The selfless love warms victims and encourage them to rebuild home.
