Star Trek Charities

I wonder what kind of charities they have in the Star Trek universe. I mean they appear to have solved world hunger and the middle east's problems. Medicine had advanced such that the only things it seemed they couldn't cure by waving around a blinking light we would classify under "act of God" today. I suppose you'll still get your regular disaster benefits when there's a hurricane or something but overall, it's got to put a real damper on charities. Do you think celebrities go on game shows and donate their winnings to charities for things like upset stomach or speak out at rallies against bland food?
