Housing Crisis
(lemmy.world)
Based on currently available numbers, there are about 31 vacant housing units for every homeless person in the U.S.
That assumes it takes a full year after buying the property to fully move into it. If we cut that number in half ( 1/16 of homes, or 7.87M homes) that provides more than enough homes for the homeless population and assumes 6 months for people to move which is still absurdly long.
