Personally, I was asked to submit suggestions of charities to Larry. But it was made clear to me that there had to be some benefit - preferably large ROI, since small ROI wasn't worth Larry's time. And, while it was possible to occasionally ignore ROI, there had to be a good reason to do so (in particular, if I could find something that Larry personally cared about or had the potential to have large ROI soon or influence a particular CEO who might be a customer.) So when I made a list of charities I thought were worthwhile, I couldn't justify submitting any of them to Larry. So I never got more involved with our charitable giving. What could have been the opportunity of a lifetime simply left me more jaded about our Capitalist system.
