Bill Gates' charitable work comes to mind. I wouldn't call him really a robber baron as the term implies wealth gained unfairly or from others involuntarily. The Fed is printing almost another half trillion in cash to inject, subsidize Wall St., for example. I also don't know if the term applies fairly to Samsung, as while the Korean history of chaebol companies was fueled by crony capitalism, their wealth does primarily come from their export-driven business where they compete globally. It's not like a JP Morgan (the person) or JP Morgan (the Wall St bank today) who really rely on borderline slavery from captive labor markets, or welfare from taxpayers.
