Money given today pays dividends in the lives of those who benefit and the lives of people who are around them, it just doesn't show up on any balance sheet. The after school program that provides the missing support network for a child, keeping them out of a street gang and later prison, and helping them develop the skills to find gainful employment pays hidden dividends of tens or hundreds of thousands of dollars for society. Also there are second and third order effects that amplify those gains further. If that money was instead earning 5% in an endowment fund, it may keep the name of a robber baron alive for perpetuity, but it does far less for society today. And if you could trace the knock-on effects of the money given today, you would likely find that the benefits distributed throughout society accumulate quicker than the 5% rate of growth achieved by that endowment fund.
