The contrast of Silicon Valley "young" philanthropists with the grand giving of Wall Street establishment typifies the difference between the young and old philanthrocapitalists.
"The tech world is home to some of the planet’s wealthiest entrepreneurs and most dynamic philanthropists, 21st-century heirs to Carnegie and Rockefeller who say they can apply the same ingenuity and zeal that made them rich to making the rest of the world less poor. San Francisco also has one of the highest levels of income inequality in the nation, with the wealth distortion most concentrated among the very people who are driving the economy as a whole.
"A similar paradox seeps into philanthropy. Tech entrepreneurs believe their charitable giving is bolder, bigger and more data-driven than anywhere else — and in many ways it is. But despite their flair for disruption, these philanthropists are no more interested in radical change than their more conservative predecessors. They don’t lobby for the redistribution of wealth; instead, they see poverty and inequality as an engineering problem, and the solution is their own brain power, not a tithe."--Alessandra Stanley, The New York Times
