Charity v Foundation v Philanthropy
I am not an expert on what words mean, I do have my own idea of what these words roughly mean, and what the differences are. And I stress, this is my perception.
Charity: The masses give. Collection tins on shop counters. Loads of small donations. Mixture of immediate help and long term. Mainly volunteers.
Foundation : Set up by wealthy donors in the first instance, and ongoing funding by wealthy people. No high street tin shakers, Instead they do black tie fundraisers or solicit rich individuals. Fund research grants etc, rather than direct action. Paid staff.
Philanthropy : Where a very rich individual with an awful lot of money gives it away to the above 2, among others. Paid staff, or pay other orgs to have pay staff.
After writing the above I did look them up in a dictionary, and while there is a lot of overlap, the above is not a million miles away.
So when the Sussexes change from a foundation to philanthropy , it might not technically run afoul of definitions, but in my mind, it is certainly stretching them.
And we are not talking massive money here. Their most recent tax returns show about 6 million raised ( from 1 unknown donor apparently), over half of that going to admin costs. No info I can see on what is being funded.
After admin, we are talking in the region of $3million. And I done a google for a comparison, that's about 1/3 of the North York Moors railway turnover.
So the Sussexes Philanthropy org, is smaller than a heritage railway.
