The billionaire often criticizes the
Salvation Army because if he donates money (which he will NEVER do) the donation will not be in "his/her name" and the
Salvation Army will get the "credit" for his donation.
The billionaire is greedy for a non-greedy person would not care as long as it would go to the betterment of a person in need.
In an extreme case of greediness the billionaire may try to make it seem like donating to the
Salvation Army is a scam and they keep the money for themselves.
