Why is it that every time someone goes through a bad point in life, they have to start a foundation?

When family members and friends die from suicide, drug abuse, sickness or what have you, the family feels a need to make ANOTHER foundation just for that reason. "My daughter died from a disease that kills less than a 1000 people a year, give money to my foundation." There are hundreds of foundations out there and making another will not change anything. Sorry you kid died from cancer but making a new organization will not help others. I understand mourning but come on, do I have to make a new foundation and take donations every time someone dies? In the news you will hear about how a parent loses a child and now they will start a new foundation in his or her memory. What ever happened to a headstone? If the other foundations that where made in other people's memory did not help you, what makes you think YOUR'S will help others? You can't stop bad things from happening to loved ones and throwing money at problems will not prevent tragedies. At worst I feel like people make these new charities to make money and profit from loss.
