So virtually all of the poverty alleviation has happened when governments have prioritized access to basics (housing, education, healthcare, public transport, pensions, wage regulations, utilities like power/water/sewerage, etc) to the common people rather than leave it up to "market forces".
Institutions that represent the interests of people using state budgets for inclusive policy have a much bigger role in poverty alleviation, by creating an environment of fair opportunity for the poor, than explicit deregulation/privatization.
