Philanthropy is complex with no simple definitions or policies. While philanthropy aims to improve society, it is voluntary in nature and cannot replace public spending. Tax incentives for philanthropy are justified not as subsidies for services but to encourage a pluralistic civil society. Philanthropy is often inherently political through addressing societal problems, and this type of campaigning is valuable though controversial. Progressive philanthropy seeks social change rather than status quo but faces challenges around conservative donors and power imbalances.
