Goldman Sachs is to increase its charitable giving, setting aside $200 million to nearly double the size of its main foundation. The move would seem to be a response to recent criticisms over the firm’s anticipated profits and bonuses. Whether it will have the effect of disarming any public furore is doubtful, however, since the sum is trivial by comparison: in the first nine months of this year, the firm set aside about $17 billion for bonuses and other compensation.
