Charity is given to God and he gives the blessings. Now whether the MS foundation is a scam, I cannot say, I only know that many like me are suffering on a day to day basis. I am the lucky one as I cured myself in the early stages but I must be constantly on guard.
So I am sorry for your experience but know that if you gave $5000 then you will take blessings from the creator and if they don't help you then realize there are millions in need and just maybe that is all anyone is getting. Yes, all CEO's get outrageous salaries. But compared to some charities such as Red cross that is still minimal.
People run to send money to red cross when Katrina struck. How much did the people actually get, see Louisiana is still in shambles, so we do what we can when we can and if we walk one day with intent in our heart then the blessings come to us and if the people abuse the funds then so be it, but I did my part.
