Elizabeth Svoboda is a contributing writer for Globe Ideas. Her upcoming book, “The Art of Pacing,” is about setting a sustainable pace in a fast-forwarded world. There’s a Monopoly-man image in the public mind of what a philanthropist looks like — someone like John D. Rockefeller, who funneled his oil wealth into high-profile foundations, or finance heir J.P. Morgan Jr., who parceled out large donations to churches, hospitals, and museums.
