I realize that saying that we should be grateful while we have so much seems empty and hippocritical. I have done service trips before, and spent time with people who have fallen through all the cracks. I often feel guilty that I am chosen to lead a life of plenty and of enjoyment, while so many others are suffering.
The first step to rectifing the problems in our world is exposure, and then action. I definitly have not dedicated my life to the poor or less fortunate,nor am I ready to, but I feel I have done a little to better the situation of a few.
The criticism in this case seems to be motivated by jealousy, not a genuine concern for those less fortunate.
