How important is philanthropy?
Microsoft co-founder Paul Allen has said he will commit the majority of his estimated $13.5bn (£8.8bn) fortune to philanthropy after his death. Are we too dependent on philanthropists?
Mr Allen follows fellow co-founder Bill Gates in pledging billions of dollars to projects designed to help others.
In the UK, the government hopes charitable giving will help plug a funding gap of up to 30%, but it has emerged that some of the country's leading philanthropists have warned that such an ambition is overly optimistic.
Do you welcome the support of philanthropists or is it something we should be concerned about? Are we becoming over reliant on philanthropists?
