The law of supply and demand dictates that if a good is abundant (i.e., more exists than people need), its price will fall towards zero/free.
There is also a product called LifeStraw, which converts contaminated water into free, safe, filtered, drinkable water. If this product were made easily and cheaply available to the third world, perhaps through charity or mutual aid, then struggling people would have a much easier time acquiring water, one of the most primary things we need to survive.
There are now 6 empty residences for each homeless American. Remove all government supports (including police protection) for absentee property ownership. Allow people to host homeless and needy people in their apartments without requiring them to pay rent, and allow renters and trailer and tiny house residents to claim state homestead tax credits (in states other than Wisconsin, the only state in which residents can do so).
