If 60,000 people who attend/want to attend a FB game, donated an additional $500, the shortfall would be taken care of.
60,000 * $500 = $30,000,000
Yes, but that's sort a Utopian view of philanthropy- it doesn't work like that, especially in the current environment. Heck, the old 80/20 adage where 80% of your fundraising dollars come from 20% of your donor base is being challenged. It's closer to 90/10 with fewer low to mid-level donors.
